1
Q

Aerobic Respiration

A

Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process.

2
Q

Anaerobic respiration

A

Anaerobic respiration is respiration using electron acceptors other than molecular oxygen.

3
Q

Stages of Aerobic Respiration

A

There are three stages in the process of transforming glucose to ATP:

  • Glycolysis
  • The citric acid cycle
  • The electron transport chain.
4
Q

Krebs Cycle

A

The citric acid cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.

5
Q

Kreb Cycle Steps

A
  • dehydration
  • hydration
  • decarboxylation reactions.
6
Q

Oxidative Phosphorylation

A
  • occurs on cristate of mitochondria
  • energy rich H-atoms are transferred from 1 hydrogen acceptor to the next.
  • the final hydrogen acceptor is oxygen forming H2O
7
Q

Differences between Aerobic & Anaerobic Respiration

A
  • Aerobic Respiration only occurs in oxygen
  • In Aerobic Respiration, a large amount of energy is released because the molecule is completely broken down.
  • Anaerobic Respiration occurs in the absence of oxygen.
  • In Anaerobic Respiration, a small amount of energy is released because the glucose molecule is only broken down partially
8
Q

The products of Aerobic are…

A
  • carbon dioxide

- oxygen

9
Q

Anaerobic Respiration provides..

A
  • lactic acid
  • carbon dioxide
  • ethanol
10
Q

Anaerobic Respiration in muscle exercise

A
  • during vigorous exercises
  • glucose is broken down
  • pyruvic acid is formed
11
Q

Anaerobic Respiration in plants

A
  • only glycolysis occurs.
  • glucose is broken down
  • pyruvic acid is formed
  • CO2 is released
12
Q

Lactic Acid Fermentation

A
  • a toxin that leads to muscle stiffness and muscle pain

- oxygen is needed to convert the lactic acid back to pyruvic acid.
