Cystathioninuria can be caused by two different mutations in the enzyme cystathionase. Cystathioninuria caused by mutation 1 can be overcome by providing cells with increasing concentrations of the coenzyme pyridoxal phosphate. Which of the following statements describe the most likely changes in the binding affinities of the two mutant enzymes?
A. Both mutant enzymes have lost the ability to bind the substrates.
B. The enzyme with mutation 1 has lost the ability to bind to the substrates, whereas the enzyme with mutation 2 has lost the ability to bind to pyridoxal phosphate.
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
D. Both mutant enzymes have lost the ability to bind pyridoxal phosphate.
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.

Put the following steps of Meiosis in the correct order:
I. The cell divides into 2 daughter cells
II. Homologous chromosomes pair up in the center of the cell
III. Spindle fibers separate homologous chromosomes
IV. Chromosomes become shorter and thicker
A. I, II, III, IV
B. IV, III, II, I
C. II, III, I, IV
D. IV, II, III, I
What is Meiosis
Meiosis (listen); from Ancient Greek'lessening', since it is a reductional division) is a special type of cell division of germ cells in reproducing organisms that produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Additionally, before the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilization, the haploid cells produced by meiosis between a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.
Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

Write the definition of the rate of ATP hydrolyzation, R, in your own words. How would you calculate the rate of ATP hydrolyzation, R, if you know the step size of the motor protein, s, and the average vesicle velocity, v
Answer:
ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting
R = Vesicle velocity / step size
Explanation:
The rate of ATP hydrolyzation can be explained by relating ΔG ( Gibbs free energy) and Q using this equation : ΔrGo + RT ln(Q). where ΔrGo = standard Gibbs energy change.
while ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting

In sweet peas, the genes for flower color and pollen grain shape are 11 cM apart. A pure-breeding purple flowering plant with round pollen grains is crossed to a pure-breeding red flowering plant with long pollen grains. The resulting F1 offspring are all purple flowering plants with long pollen grains. What percent of offspring from a test cross analysis of the F1 individuals would you expect to be purple flowering plants with long pollen grains
Answer:
The correct answer is - 44.5%.
Explanation:
In this question, there are two traits are given, flower color and pollen shape. The purple flowers and long pollen are wild-type (dominant). Red flowers and round pollen are mutant or recessive. The cross is between a pure breeding purple and round pollen plant with red and long pollen plant. The offspring are all purple and long pollen plants. However, the offspring would be all heterozygotes genotype for both traits.
Linkage can be calculated as -
Linkage distance = % of recombinant offsprings formed in a test cross.
parental types are purple and long pollen, red and round pollen.
So, the recombinant type would be purple and round pollen, red and long pollen.
11% of the offspring would be recombinant type as the distance is 11cM. Therefore, 89% of the progeny would be parental type. Which means this 89% of parental offsprings have equal proportions of both phenotypes of parents. So, the purple flowers and long pollen would be half of 89%.
that is 89/2 = 44.5%.

The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __ 1 __ _. The organisms that consume these are called __ 2 __ _ (it should end in -ores) which occur at the ___ 3 ___ trophic level. The number of trophic levels that any ecological system will primarily dependent on the __4__ organisms.
Answer:
The organisms that harness non-biological energy and convert it to biologically relevant/useful energy are called __autotrophos or producers_. The organisms that consume these are called _herbivores_ (it should end in -ores) which occur at the __second_ trophic level. The number of trophic levels that any ecological system will primarily dependent on the _consumer_ organisms.
Explanation:
In the trophic web occurs energy transference through organisms occupying different levels in the chain. Each level feeds on the preceding one and becomes food for the next one. The first link is occupied by autotroph organisms, which are the producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
Every link has an effect on the superior links and the immediately anterior link, meaning that whenever one of the links changes, the other ones will be affected.
Autotrophs or producers synthesize inorganic substances, such as light, and turn them into organic matter according to their own needs. These organisms are photoautotrophs, such as plants, or chemoautotrophs. They occur at the first trophic level.
Heterotrophs are those incapable of producing their own organic matter, so they feed on producers, depending on them to get proteins and energy. In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers. These animals can be herbivorous, carnivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.
In the particular case of herbivores, they occur at the second throphic level feeding on producers and being eaten by carnivores.
In general, most trophic chains are composed of 4 or 5 levels, depending on the number of consumers present, and the energy transference between levels.

What do you think will happen to the convention currents in the mantle if the interior of Earth eventually cools down
Answer:
No convention currents occur.
Explanation:
If the interior part of the Earth is cool down, it will leads to convection currents to stop. Due to this cool down of the earth's interior part cease the motion of the plates and the Earth would become geologically dead. Convection currents within the Earth's mantle occurs when the hot material rising upwards and then dropping back toward the core due to cooling so if the mantle is cool so no movement occurs as well as no convention currents.
Under normal conditions the sympathetic division is usually active in the body resting heart rates are influenced by nor epinephrine the parasympathetic system keeps heart rate lower than the heart would beat on its own. all of the above are true
Answer:
the parasympathetic system keeps heart rate lower than the heart would beat on its own.
Explanation:
The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.
