If a normal plant were put in a dark room , why would the Calvin cycle eventually stop
B: the plant would be unable to take in a carbon dioxide
C: the product of the light reaction are needed for the Calvin cycle to occur
D: the Calvin cycle would never stop, unless you stop watering the plant
Answer:
C
Explanation:
Just took the test good luck
If the normal plant were kept in a dark room then Calvin cycle eventually stop as the product of the light reaction are needed for the Calvin cycle to occur. The correct option is C.
What is Calvin cycle?Carbon atoms from CO2 used to build three-carbon sugars in the Calvin cycle. This process is powered by and dependent on the light reactions' ATP and NADPH.
If the normal plant were kept in a dark room then Calvin cycle eventually stop as the product of the light reaction are needed for the Calvin cycle to occur.

Answer:
protons against a concentration gradient.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Hence, during cellular respiration, most adenosine triphosphate (ATP) is formed as a direct result of the net movement of protons against a concentration gradient in the electron transport chain.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Through the process of chemiosmosis, the H+ gradient is used to produce ATP molecules. During cell respiration, most ATP is formed as a direct result of the net movement of hydrogen ions down a concentration gradient.
---------------------------------
Let us review the oxidative phosphorylation process.
The electron transporter chain + chemiosmosis constitute the process of oxidative phosphorylation.
Chemiosimosis refers to the ATP production through a proton gradient
The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane. It constitutes a series of enzymatic reactions to release and save energy for the organism’s correct functioning.
Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.
Different redox reactions occur to pass electrons along the chain.
Released energy creates a proton concentration gradient used to synthesize ATP.
1) NADH provides electrons to the first complex, Complex I. From there, electrons go to the coenzyme Q that carries them to complex II. Meanwhile, complex I pomp four protons to the intermembrane space.
2) Complex II receives electrons from CoQ and also receives electrons from FADH2. Electrons are sent from complex II to ubiquinone Q that carries these electrons to complex III.
3) Complex III receives electrons from ubiquinone Q and pomps protons to the intermembrane space. Electrons are transferred to Cytochrome c.
Electrons travel from cytochrome c to complex IV.
4) Complex IV is the last complex that pomps protons to the intermembrane space.
5) Electrons are sent to O₂ molecules, which also receive protons in the matrix to create water molecules. Four electrons are needed to produce two water molecules from one O₂ molecule.
Since too many protons were pumped to the intermembrane space by complexes I, III and IV, an electrochemical gradient is created.
Protons tend to go back to the matrix, but they can only pass the membrane through an integral membrane protein.
H+ returns to the mitochondrial matrix through the ATP synthase.
While H+ passes to the matrix, ATP is produced by this Chemiosmotic process.

Which statement below best describes the difference between "cytokinesis" in animal cells and plant cells? (choose all that apply)
In animal cells a cell plate forms and the cells do NOT pinch apart
There is not a difference in cytokinesis in plant and animal cells
In animal cells a cleavage furrow forms and the new cells pinch apart
In plant cells a cell plate forms, the new cells do NOT pinch apart
The difference between cytokinesis in animal and plant cells is that a cleavage furrow forms in animal cells and the new cells pinch apart.
Cytokinesis is the division of cytoplasm at the end of mitosis leading to the production of 2 independent daughter cells from a single cell.
Animal cells lack a cell wall. Thus, the cell membrane bends inward to form a cleavage furrow that eventually leads to the separation of the new cells.
The presence of a cell wall in plant cells means that a cleavage furrow cannot be formed like animal cells. Instead, a new cell wall, otherwise known as the cell plate, just forms to separate the two nuclei at the opposite poles of the mother cell.

Answer:
Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

what type is anomer?
Answer:
An anomer is a type of geometric variation found at certain atoms in carbohydrate molecules. An epimer is a stereoisomer that differs in configuration at any single stereogenic center. An anomer is an epimer at the hemiacetal/hemiketal carbon in a cyclic saccharide, an atom called the anomeric carbon.The anomeric carbon is the carbon derived from the carbonyl carbon compound (the ketone or aldehyde functional group) of the open-chain form of the carbohydrate molecule. Anomerization is the process of conversion of one anomer to the other. As is typical for stereoisomeric compounds, different anomers have different physical properties, melting points and specific rotations.

What is one reason the membrane proteins could not go where the Davson-Danielli model thought they should go, sandwiching the lipid membrane on either side? A. Proteins are hydrophobic, so they shouldn’t be in an aqueous environment. B. Proteins are not normally found in cells. C. There was not enough protein to cover both sides of the membrane. D. They were correct, the proteins do go there.
Answer: A. Proteins are hydrophobic, so they shouldn’t be in an aqueous environment.
Explanation: ummm Founder Education
Membrane proteins are part of the biological membranes. Proteins are hydrophobic, and lacking in an aqueous environment was the drawback of the Davson-Danielli model. Thus, option A is correct.
What is Davson-Danielli model?
Davson-Danielli gave the membrane model, which was also called a lipoprotein sandwich model. It was proposed to show the selective nature of the membrane structure and resembles a sandwich due to its structural organization.
The lipids were layered in between the two protein layers on either side making it look like a sandwich, but the model was rejected as it didn't explain certain permeable molecules.
The arrangement was also contradictory as the proteins are hydrophobic and were placed on the outer side making them exposed to the water molecules. This constricted the movement, and the model failed.
Therefore, the hydrophobic nature of the protein failed the Davson-Danielli model.

All living organisms break down sugar to obtain energy using cellular respiration, Which of the following chemical reactions represents the process of aerobic cellular respiration
Answer:
The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy
Explanation:
Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.
Glucose is the main energetic substrate to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:
C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + ATP ↑
Glucose + Oxygen → Water + Carbon dioxide + Energy ↑
This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.
The other reactions:
oxygen + water → glucose + lactose glucose + lactose → oxygen + water water + carbon dioxide + energy → oxygen + glucosedo not represent the components or the order of the reactions that occur in aerobic cell respiration
