Cell Respiration

mitochondria

where aerobic respiration takes place

aerobic

requires oxygen

anaerobic

without oxygen

glycolysis

1st step in CR, glucose if broken down

Kreb cycle

second stage of cellular respiration, in which pyruvic acid is broken down, occurs in the matrix of mitochondria

E.T.C.

3rd stage, occurs in inner membrane

pyruvate

Three-carbon compound that forms as an end product of glycolysis.

NADH

electron carrier that stores energy used to make ATP

Ethyl alcohol

result of fermentation carried out by plants, and yeast

Lactic acid

product of fermentation in animal muscle cells

Acetyl CoA

enzyme used to breakdown pyruvate

Net yield of ATP during glycolysis

2 ATP

34-38

number of ATP made during E.T.C.

FADH2

electron carrier produced during the Krebs cycle

glycolysis used

glucose and 2ATP

glycolysis produced

NADH, 4ATP, 2pyruvate

Kreb cycle used

pyruvate

The Krebs cycle produces

ATP, NADH, FADH2, CO2

E.T.C. uses

NADH, FADH2, O2

E.T.C. produces

ATP and H2O

Two types of respiration

aerobic and anaerobic

Where does glycolysis occur?

cytoplasm

Total yield of ATP during glycolysis

4 ATP
