Q

cell respiration steps

A
  1. glycolysis 2. formation of acetyl of CoA 3. Krebs cycle 4. oxidative phosphorylation
35
Q

glycolysis

A

split into 2-3 carbon molecules called pyruvic acid, 2 ATP, occurs in cytoplasm, 2 NADH

36
Q

aerobic respiration

A

pyruvic acid transported to mitochondrion, p acid + coenzyme A- acetyl CoA, carbons leave cell in CO2, 2 NADH produced

37
Q

Krebs cycle

A

all carbons converted to CO2, occurs in matrix of mitochondrion, acetyl combines with oxaloacetate to form citric acid (6),

38
Q

what does krebs cycle produce

A

1 ATP, 3 NADH, 1 FADH2, total of 4 ATP

39
Q

anaerobic respiration

A

lactic acid & fermentation, ethyl alcohol & CO2, makes no ATP

40
Q

light reactions

A

on thylakoids, cyclic and nc, P1 & P2

41
Q

chemiosmosis

A

electrochemical gradient of H ions used to synthesize ATP

42
Q

dark reactions

A

in stroma, changes from acid to aldehyde, RUBP & PGAL, stomata closed on hot dry days

43
Q

CAM

A

cacti, succulents, keep stomata closed during day to conserve H2O, open at night
