Quiz 4

Question 1

Give the general equation for aerobic respiration. That is if I’m looking you or at a cell, what do I see entering and leaving?

Answer 1

food or glucose + O2 —> CO2 + H2O

Question 2

Describe the general cellular function of both NAD+/NADH and FAD/FADH2

Answer 2

NAD+ and FAD are oxidizers, the take electrons to things

NADH and FADH2 are the reducers, they reduce things by donating electrons to them

Question 3

Give the inputs and outputs of the Energy Investment phase of glycolysis

Answer 3

Glucose + ATP –> Glyceraldehyde 3-p (G3P) + ADP

Question 4

Give the inputs and outputs of the Energy Payoff phase of Glycolysis

Answer 4

G3P + NAD+ ADP —> Pyruvate + NADH + ATP

Question 5

the products of pyruvate oxidation are CO2, NADH, and

Answer 5

Acetyl CoA

Question 6

Diagram the process of oxidative phosphorylation as described. Include the protein complexes (i-iv), how the electrons flow through the proteins, where NADH and FADH2 donate their electrons, where oxygen enters and water leaves, the creation of the hydrogen ion gradient, and the activity of the ATP synthase:

Answer 6

first protein NADH -> NAD+ goes arrow to e- and arrow out is pointed at H+
Arrow out from e- to an e- in the middle then arrow from that to another long protein H+ enters from bottom and exits at top using the arrow
small circle e- between the two long proteins arrow pointing at it from bottom with FADH2 -> FAD
arrow from e- in the little cricle pointing at 2nd long protein
2nd long protein e- arrow going to another cirlce e- between two and three that arrow then goes to protein three where h+ enters from bottom leaves from top
arrow from e- in three goes out and O2+H+ -> H20
fourth protein has ATP Synthase written inside and h+ enters from top nad exits at bottm
on bottom of protein but after the membraze ADP+Pi –> ATP
