Question

What would you predict would be the optimal temperature of most enzymes that occurs in humans? Select one: a. 45 degrees Fahrenheit b. 32 degrees Fahrenheit c. 58 degrees Fahrenheit d. 73 degrees Fahrenheit e. 98 degrees Fahrenheit When you cook an egg the protein in the white of the egg changes appearance from a clear liquid to a white solid. What has happened to the egg protein? Select one: a. It is denatured b. The shape of the protein is altered c. Nothing, you cannot affect an enzyme by heating it d. Both A and B Where is energy stored in living organisms? Select one: a. In blood b. In the bonds of biological molecules c. In nerve tissue d. Energy cannot be stored Which molecule is considered the most common short-term energy carrier molecule of cells? Select one: a. Catalase b. Oxygen c. ATP (Adenosine Triphosphate) d. Enzymes e. Starch Which of the following s true according to the 1st and 2nd law of thermodynamics? a. Energy conversions are 100% efficient b. The potential energy of the final state will always be more than the potential energy of the init al state c. The energy available to do useful work is less after energy is transformed d. Energy can be created e. Energy can be destroyed

Explanation / Answer

Ans :-1) (e) 98 Degrees Fahrenheit.

Because our body tempreture is 370c. and enzymes are sensitive to their environmental conditions. At extremes of pH or temperature, either high or low, the native structure of the enzyme will be compromised, and the molecule will become inactive.hence the optimal tempreture of enzyme that occure in humans is 98 degree Fahrenheit.

Ans :- 2) (d) Both A and B

Because Egg white contain the protein.and when we cook the egg the proteins can be folded in a number of different ways. the same exact chains of amino acids assembled in the same order can conform to a wide variety of different shapes.

When an egg is heated or boiled, the proteins in the yolk and albumen are denatured. The existing bonds in the proteins break, and new bonds are formed.

Ans :- 3 ) (b) in the bond of biological molecule.

Energy stored in the living organism in the bond of biological molecule such as the ATP ,ADP ,GTP ,Phosphate bond etc.

Ans :- 4 ) (c) ATP. (Adenosine triphosphate )

Adenosine triphosphate is a nucleotide composed of a sugar, phosphate, and nitrogen base (ribose, 3 phosphates, adenine)it is not used by other cells and is for short-term storage not for long-term energy storage.
