Chapter 9

Question 1

Cellular respiration

Answer 1

The catabolic pathways that breaks down organic fuel to produce atp with the assistance of ETC

Question 2

Aerobic respiration

Answer 2

Degrades organic molecules to yield ATP
Uses ETC and O2 as final electron receptor

Question 3

Anaerobic Respiration

Answer 3

Utilizes ETC but the final electron receptor is not O

Question 4

Glycolysis

Answer 4

Aerobic respiration

Breaks down glucose into 2 molecules of pyruvate
Occurs in the cytoplasm. —2 major phases——
—energy investment. — energy pay off

Initial cascade

Question 5

Krebs Cycle/ Citric acid cycle

Answer 5

Completes the break down of pyruvate to CO2
Oxidizes organic fuel from pyruvate— generating 1 ATP
8 steps-each specific enzyme
Coenzyme Acetyl COAq
The transport of pyruvate into the mitochondrion

Question 6

Electron Transport Chain / ETC

Answer 6

Integral; protiens embedded in inner membrane (cristae) of mitochondria

Protiens accept electrons from H

NADH and FADH donate electron to the ETC

Question 7

Oxidation

Answer 7

Substances loses electrons

Question 8

Redox

Answer 8

Substance gains electrons (amount of positive charge is reduced)

Question 9

Fermentation

Answer 9

Lacking ETC
Uses substrate level phosphorylation to generate ATP

Final electron acceptor is pyruvate- glucose is not completely oxidized

3 products of fermentation
Alcohol
Gas
Acid
