ATP production during glycolysis requires an enzyme occurs i

ATP production during glycolysis;

requires an enzyme

occurs in the cytosol

occurs via substrate-level phosphorylation

all of the above

The reactions of the Krebs cycle occur in the:

Inner membrane of the mitochondria

Intermembrane space of the mitochondria

The cycoplasm

The matrix of the mitochondria

The movement of electrons down the electron transport chain

Is used to make acetyl-CoA

Generates CO2

Produces an electron gradient

Pumps protons into the intermembrane space

Which of the following accurately describes a distinction between lactic acid fermentation and alcoholic (ethanol) fermentation?

Lactic acid fermentation occurs in prokaryotes, whereas alcoholic (ethanol) fermentation occurs in eukaryotes

The final electron acceptor in lactic acid fermentation is pyruvate; the final electron acceptor in alcoholic (ethanol) fermentation is acetaldehyde

In lactic acid fermentation, NADH is produced by glycolysis; in alcoholic (ethanol) fermentation, NADH is produced by the Krebs cycle

In lactic acid fermentation, cell use CO2 in place of oxygen; in alcoholic (ethanol) fermentation, cells use SO4

Which pathway is see in both fermentation and aerobic respiration?

Krebs cycle

Electron transport

Glycolysis

Pyruvate oxidation

Solution

(1) all of the above

(2)The matrix of the mitochondria

(3) Pumps protons into the intermembrane space

(4) The final electron acceptor in lactic acid fermentation is pyruvate; the final electron acceptor in alcoholic (ethanol) fermentation is acetaldehyde

(5) Glycolysis
