20. A researcher claims that budding yeast are able to survive in different environments because they
produce enzymes that allow them to use different molecules as sources of matter and energy.
Which of the following statements best helps justify the researcher's claim by providing a relevant
example?
a. Yeast cells produce protein kinases, which are enzymes that catalyze the transfer of phosphate
groups from ATP to protein substrates.
b. Yeast cells produce DNA polymerases, which are enzymes that catalyze the conversion of free
nucleotides into strands of DNA.
c. Yeast cells produce invertase, which is an enzyme that catalyzes the conversion of the
disaccharide sucrose into glucose and fructose.
d Yeast cells produce catalase, which is an enzyme that catalyzes the conversion of hydrogen
peroxide into water and oxygen gas.
