The reason how an enzyme cofactor needed for an essential process is an essential nutrient for only some animals. Introduction: A coenzyme is an organic non-protein compound that binds with an enzyme to catalyze a reaction. Many coenzymes, though not all, are vitamins or derived from vitamins. Thus, the enzyme cofactors play an important role in performing normal physiological processes in their system. Most of the animals can synthesize these enzyme cofactors in their own body, but some require their supply through diet.

Summary Introduction

To determine: The reason how an enzyme cofactor needed for an essential process is an essential nutrient for only some animals.

Introduction: A coenzyme is an organic non-protein compound that binds with an enzyme to catalyze a reaction. Many coenzymes, though not all, are vitamins or derived from vitamins. Thus, the enzyme cofactors play an important role in performing normal physiological processes in their system. Most of the animals can synthesize these enzyme cofactors in their own body, but some require their supply through diet.

Expert Solution & Answer

Explanation of Solution

Essential nutrients are the nutrients that cannot be synthesized by the body but required to carry out the normal physiological functions and must be provided through diet. There are six essential nutrients: carbohydrates, fats, proteins, vitamins, minerals, and water. Coenzymes primarily function as helper molecules in enzyme-catalyzed reactions. Most of the coenzymes are the vitamins (Vitamins A, C, B₁, B₂, B₃, B₆, B₁₂, H, and K) or vitamin derivatives (NADH, FADH, Quinine, and CoA).

Many animals can produce most of the vitamins they need such as vitamin B3, vitamin C, and vitamin D on their own. But some of the animals cannot synthesize some vitamins or vitamin-derived cofactors, which are thus essential nutrients for them, and they need to intake these in their diet.

For example, anthropoid primates (humans, monkeys, and apes), guinea pigs, particular Indian fruit-eating bat, and some birds do not possess the ability to synthesize Vitamin C because of a defective mutation in the gene controlling the synthesis of L-gulonolactone oxidase (GLO gene) that blocks the conversion of glucose to ascorbic acid.
The common ancestor of birds and mammals today live in an environment with abundance of green plants containing thiamine. Hence, they lost the gene responsible for the production of Vitamin B₁ (thiamine) in their own body. Thus, Vitamin B₁ became an essential nutrient for them.

Conclusion

The cofactors are needed as an essential nutrient in some animals that lack the ability to produce enzyme cofactors in their own body.

What are the three kinds of enzyme-controlled reactions so that the chemical-bond energy from a certain nutrient is released to the cell in the form of ATP?

Which of the following is true of all allosteric enzymes? They have more than one active site on each subunit. They consist of proteins only. They have a nonprotein portion. Binding at one site affects the protein function at a second site. Which of the following explains why glycosides do not undergo mutarotation? There are no longer any stereocenters. There is no longer an anomeric carbon. The ring structure does not open to become the open-chain structure. None of the above is correct.

In the lactase simulation you conducted in Part 1 of this Nutrition Lab, you found that enzyme activity is dependent upon the temperature of the environment. For Part 2 (today's experiment), what would have happened if you had refrigerated your samples, keeping them at a temperature of 4°C (39.2°F) instead of at room temperature? The test strip would change from turquoise to green, tan, or brown for all samples. The test strip would change from turquoise to green, tan, or brown for at least two samples. The test strip would remain turquoise (no color change) for all samples.
