Describe the chemistry of two types of enzymes and explain how the apoenzyme forms 200-500 words APA Format​

Answers

Answer:

Enzymes can be defined as biological polymers that catalyze biochemical reactions.”

Majority of enzymes are proteins with catalytic capabilities crucial to perform different processes. Metabolic processes and other chemical reactions in the cell are carried out by a set of enzymes that are necessary to sustain life.  

The initial stage of metabolic process depends upon the enzymes, which react with a molecule and is called the substrate. Enzymes convert the substrates into other distinct molecules and are called the products.  

The regulation of enzymes has been a key element in clinical diagnosis because of their role in maintaining life processes. The macromolecular components of all enzymes consist of protein, except in the class of RNA catalysts called ribozymes. The word ribozyme is derived from the ribonucleic acid enzyme. Many ribozymes are molecules of ribonucleic acid, which catalyze reactions in one of their own bonds or among other RNAs.

Enzymes are found in all tissues and fluids of the body. Catalysis of all reactions taking place in metabolic pathways are carried out by intracellular enzymes. The enzymes in plasma membrane govern the catalysis in the cells as a response to cellular signals and enzymes in the circulatory system regulate clotting of blood. Most of the critical life processes are established on the functions of enzymes.

Enzyme Structure

Enzymes are a linear chain of amino acids, which give rise to a three-dimensional structure. The sequence of amino acids specifies the structure, which in turn identifies the catalytic activity of the enzyme. Upon heating, enzyme’s structure denatures, resulting in a loss of enzyme activity, that typically is associated with temperature.  

Compared to its substrates, enzymes are typically large with varying sizes, ranging from 62 amino acid residues to an average of 2500 residues found in fatty acid synthase. Only a small section of the structure is involved in catalysis and is situated next to the binding sites. The catalytic site and binding site together constitute the enzyme’s active site. A small number of ribozymes exist which serve as an RNA-based biological catalyst. It reacts in complex with proteins.

D. Lamellae, gills, respiratory system, fish, pillar cells

Answers

Answer:

B

Explanation:

Cats Dont have gills so rule out C. The body has to be the end so it would be B starting from Pillar cells to fish

Biological structures are arranged based on the level of the organization. The order of organization from smallest to largest is pillar cells, lamellae, gills, respiratory system, and fish. Thus, option B is correct.

What is the level of organization?

The level of organization is the arrangement of the structures based on the level of complexity. It starts from the most simple to the most complex structures. It starts with an atom and ends in an ecosystem.

Pillar cells are the simplest level that comprises the fundamental unit made of molecules. They together make the tissues or the lamellae in the fish. The tissues or the lamellae group together to make the organ and gills.

The gills combines with the other organs to make the organ system like the respiratory system, which together with various organ system makes the fish the makes a complete organism.

Therefore, the order of the organization starts with pillar cells and ends at fish.

1. How are wavelength, frequency, and energy related to each other?

Answers

Answer:

wavelength: the distance between successive crests of a wave

frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)

electromagnetic energy is used for wifi, cell phones, microwave ovens etc.

the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays

the only part we can see is visible light

visible light can be characterised by the colours of the rainbow

the longest wavelength is red and the shortest is violet

when combined, the colour is perceived as white or beige

Answer:

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.

A closed system can be described as

Answers

A system can be either closed or open: A closed system is a system that is completely isolated from its environment. This is the definition commonly used in the system literature, which we have chosen to follow.

A closed system can be described as a physical system that does not exchange matter with its surroundings, but can exchange energy.

In the context of thermodynamics and physics, a closed system refers to a system that can exchange energy with its surroundings in the form of heat or work, but does not exchange matter with the external environment. This means that the total mass of the closed system remains constant over time, as no matter is entering or leaving the system. However, energy can still be exchanged between the closed system and its surroundings.

For example, a closed container of gas that can exchange heat with its surroundings while not allowing any gas molecules to escape or enter is a closed system. Similarly, a pot of boiling water with a lid on it can be considered a closed system since water vapor (matter) is not escaping, but heat energy is being transferred through the lid. Closed systems are a fundamental concept in thermodynamics and are often used as a simplified model to analyze and understand energy exchanges without the complexities of matter flow.

Back in the 15th century in Nuremberg, lived a family with eighteen children. Eighteen!Despite their seemingly hopeless financial condition, two of them had a dream. They both wanted to pursue their talent for art, but they knew very well that their father would not be able to send either of them to Nuremberg to study at the Academy.After many long discussions the two boys, Albert and Albrecht, finally worked out a pact. They would toss a coin. The loser would go down into the nearby mines and with his earnings, support his brother while the winner would attend the Academy. And, when that brother who won the toss completed his studies, in four years, he would support the other brother at the Academy, either with sales of his art work or, if necessary, also by labouring in the mines. They tossed a coin on a Sunday morning after church. Albrecht Durer won the toss and went off to the Academy. Albert went down into the dangerous mines and for the next four years financed his brother, whose works at the Academy were almost an immediate sensation. Albrechts etchings, his wood cuts and his oils were far better than most of his professors. And by the time he graduated, he was beginning to earn a considerable sum for his commissioned works.When the young artist returned to his village, the Durer family held a festive dinner at their lawn to celebrate Albrechts triumphant homecoming. After a long and memorable meal, punctuated with music and laughter, Albrecht rose from his honoured position at the head of the table to drink a toast to his beloved brother for the years of sacrifice that had enabled him to fulfil his ambition. His closing words were, And now, Albert, blessed brother of mine, now it is your turn. Now, you can go to Nuremberg to pursue your dream, and Ill take care of you.All heads turned in eager expectation to the far end of the table where Albert sat, tears streaming down his pale face, shaking his lowered head from side to side while he sobbed and repeated, over and over, No..no.nono.Finally, Albert rose and wiped the tears from his cheeks. He glanced down the long table at the face he loved, and then holding his hands close to his right cheek, he said softly, No brother I cannot go to Nuremberg. It is too late for me. Look. Look what 4 years in the mines have done to my hands! The bones in every finger have been smashed atleast once and lately I have been suffering from arthritis so badly in my right hand that \I cannot even hold a glass to return your toast, much less make delicate lines on parchment or canvas with a pen or a brush. No, brother for me it is too lateTo pay homage to Albert for all that he had sacrificed, Albrecht Durer painstakingly drew his brothers abused hands with palms together and thin fingers stretched skywards. He called his powerful drawings simply hands, but more than 450 years later the entire world almost immediately opened their hearts to his great masterpiece and renamed his tribute of love, The Praying hands.1.
