Q1 QUESTION 1 OF 95
What is cellular metabolism?
CORRECT ANSWER
Metabolism is a controlled set of biochemical reactions that occur in living organisms in order to
maintain life
Q2 QUESTION 2 OF 95
What is the difference between catabolism and anabolism?
CORRECT ANSWER
Catabolism is the process of breaking down larger molecules into useful energy sources whereas
anabolism is the building up or biosynthesis od macromolecules from smaller molecular units into larger
complexes, most often associated with cellular growth and repair
Q3 QUESTION 3 OF 95
What are the three distinct stages in the catabolism of glucose?
CORRECT ANSWER
Glycolysis is the first step of this process and yields 2 molecules of ATP. Next, by either fermentation (or
respiration) 2 additional molecules of ATP can be produces. Last, the electron transport chain (ETC)
produces 34 ATP via an oxidative phosphorylation event at the plasma membrane.
Q4 QUESTION 4 OF 95
What are the byproducts of light reactions used for in dark reactions?
Page 2
, CORRECT ANSWER
The ATP and NADPH produced via light reactions are used in dark reactions to convert carbon dioxide
and water into organic carbon compounds as well as useful carbohydrates (a process called carbon
fixation)
Q5 QUESTION 5 OF 95
Is cellular respiration catabolic or anabolic?
CORRECT ANSWER
Catabolic
Q6 QUESTION 6 OF 95
Is lipid biosynthesis catabolic or anabolic?
CORRECT ANSWER
Anabolic
Q7 QUESTION 7 OF 95
What do metabolic reactions involve?
CORRECT ANSWER
The transfer of electrons (redox reactions)
Q8 QUESTION 8 OF 95

CORRECT ANSWER
-Reduced
-Oxidizing agent
Q9 QUESTION 9 OF 95
