Question 4

Use the following to answer questions
Choose the correct answer from the list below. Not all of the answers will be used.
-____________ pathways can be either anabolic or catabolic, depending on the energy conditions of the cell.
A)O2
B)niacin
C)phototrophs
D)ATP
E)CO2
F)coenzyme A
G)vitamins
H)amphibolic
I)ADP
J)NADPH
K)chemotrophs

Accepted Answer

Amphibolic pathways can function both as anabolic and catabolic depending on the cellular energy conditions. The other choices in the list are either molecules involved in energy transfer (ATP, ADP, NADPH), electron carriers (FAD, NADPH), cofactors (Coenzyme A), or sources of energy (O2, CO2) and not pathways themselves. Vitamins and niacin are essential micronutrients but are not directly involved in pathways. Phototrophs and chemotrophs are organisms that utilize different sources of energy for metabolism and not pathways.
