b. catabolism
c. metabolism
Value: 2
The breakdown of starch is broken down to glucose is an example of:
a. anabolism
b. catabolism
c. metabolism
Value: 3
For the following statement, determine which description best describes the process: DNA is synthesized from free nucleotides.
a. anabolism
b. catabolism
c. metabolism
Value: 4
Fill in the blank: Catabolic reactions result in the synthesis of molecules of .............via cellular respiration. This is then used to power anabolic reactions.
Value: 5

a. it is not possible to release it in a single step.
b. more total energy is released in multiple steps than would be released in a single step
c. less total energy is released in multiple steps than would be released in a single step.
d. more energy can be harvested for cellular use in multiple steps than from a single step.
