Question

2 multiple choice 20 points when an enzyme is denatured, it’s ______ is changed.
shape
substrate
chemical composition
3 multiple choice 20 points which two factors affect the function of all enzymes?
temperature and light intensity
temperature and ph
ph and carbon dioxide level

Explanation:

Question 2

Enzymes are proteins, and denaturation involves the disruption of their specific three - dimensional structure (shape). The substrate is the molecule the enzyme acts on, and denaturation doesn't change the enzyme's substrate. Also, denaturation doesn't change the chemical composition of the enzyme (the amino acid sequence remains the same, just the folding changes). So when an enzyme is denatured, its shape is changed.

Enzyme function is affected by temperature (too high or too low can denature the enzyme or reduce its activity) and pH (extreme pH values can also cause denaturation or affect the active site). Light intensity has no direct effect on enzyme function, and carbon dioxide level is not a general factor affecting all enzyme functions. So the two factors that affect the function of all enzymes are temperature and pH.

Answer:

A. shape
