1
Q

what is the process called that breaks down glucose to form ATP?

A

cellular respiration

2
Q

what are the 2 different forms of cellular respiration called?

A
  1. aerobic respiration

2. anaerobic respiration

3
Q

what is aerobic respiration?

A

respiration that requires oxygen

4
Q

what does aerobic respiration produce?

A

produces carbon dioxide, water and a lot of ATP

5
Q

what is anaerobic respiration?

A

respiration that takes place in the absence of oxygen

6
Q

what does anaerobic respiration produce in animals?

A

lactate (lactic acid) and only a little ATP

7
Q

what does anaerobic respiration produce in plants and fungi?

A

ethanol, carbon dioxide and only a little ATP

8
Q

what are the 4 stages of aerobic respiration called?

A
  1. glycolysis
  2. link reaction
  3. krebs cycle
  4. oxidative phosphorylation
9
Q

brief summary of glycolysis?

A

splitting of glucose (6-C molecule) into 2x pyruvate (3-C molecule)

10
Q

brief summary of the link reaction?

A

pyruvate (3-C molecules) enter into a series of reactions which lead to the formation of acetyleco-enzyme A (2-C molecule)

11
Q

brief summary of the krebs cycle?

A

acetylco-enzyme A is introduced into a cycle of redox reactions that produce some ATP and a large quantity of reduced NAD and reduced FAD

12
Q

brief summary of oxidative phosphorylation?

A

the electrons associated with reduced NAD and reduced FAD which were released from the Krebs cycle, are used to synthesis ATP with water (released as a by-product)
