Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway e
lisabon 2012 [21]

Answer:

Pyruvate kinase

Explanation:

Yeasts convert glycerol and sugars into glyceraldehyde 3-phosphate (G3P) through independent pathways. Then, G3P forms pyruvate and, in some circumstances, pyruvate is converted in ethanol, which can be used as energy sources. If the mutation affects any reaction before G3P formation, it will only affect yeast growing either on sugar or pyruvate but not both.

Pyruvate kinase is the only enzyme on the list acting after G3P is formed and before pyruvate is formed. All other options are enzymes acting only in the formation of G3P from sugars. Meaning that only pyruvate kinase mutants will lack the ability to grow on both sugars and glycerol.

Why doesnt pepsin, the enzyme released in the stomach to
Fiesta28 [93]

Answer: unfavourable ph condition for the pepsin

Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .

As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.

In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.

As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
