Question 1

location?

Answer 1

cytosol

Question 2

which of preparatory and payoff phases are endergonic/exergonic

Answer 2

prep: ender
payoff: exer

Question 3

Mg2+ is needed in which enzymes

Answer 3

the first 2

Question 4

which individual reactions are exergonic

Answer 4

prep: the irreversible ones
payoff: substrate level phosphorylation

Question 5

important reactions?

Answer 5

first/second priming reactions
cleavage
oxidation and phosphorylation
2x substrate level phosphorylation

Question 6

importance of glucsoe

Answer 6

oxidation makes energy and intermediates
can be stored as glycogen
many tissues and organs can meet enery needs through glucose only

Question 7

alcohol fermenation?

Answer 7

pyruvate + TTP + Mg2+ –pyruvate decarboxylase–> acetaldehyde + CO2
acetaldehyde + NADH + H+ –alcohol dehydrogenase–> ethanol + NAD+

Question 8

lactic acid fermentation?

Answer 8

pyruvate + NADH + H+ –lactate dehydrogenase–> lactate + NAD+

Question 9

oxidative decarboxylation to acetyl co a?

Answer 9

pyruvate + CoASH + TPP + lipoate + FADH + NAD+ —-pyruvate dehydrogenase complex —> acetyl coA + NADH
