Overview Of Metabolism

Question 1

What are the major functions of metabolism

Answer 1

Storage for energy

Transforming molecules

Eliminating byproducts

Question 2

Metabolic pathways

Answer 2

Catabolism = breakdown, releases energy in the process
Anabolism = synthesizes, needs energy input

Question 3

Forms of chemical energy

Answer 3

ATP
NADPH - common redox agent/e- donor
NADH - makes ATP
NADPH - for biosynthesis

Question 4

ATP is the unit of energy generated by the _____ of fuels (like glucose, AAs, FAs)

Answer 4

Oxidation

Question 5

Oxidation of glucose, FAs, AAs lead to

Answer 5

Acetyl CoA

Question 6

NADH vs NADPH

Answer 6

NADH = carries e- to ETC

NADPH = carries e- for biosythesis
