Q

describe the process of glyclosis

A
  1. glucose converted in to x2 triose phosphate
    - 2 ( ATP- ADP+pi)
  2. converted in to 2 pyravates
    - 2 NAD to HNAD
    -4(ADP+pi-ATP)

Q

how pyuravte movef from the cytoplasm to mitrochndria

A

actively transported only for aerobic respiration
- for anerobic respriation it remains in cytoplasms if oxygen is not available

Q

describe the process of link reaction

A
  1. pyruvates converted to acetate(2 carbons)
    - carbonation
    - NAD-HNAD
  2. acetate is added to coenzyme A, so a conveted Acetyl CoA

Q

describe the process of a kerb cycle

A
  1. Acetyl CoA to 6 carbons
    - coenzyme is removed
  2. 6 carbons
    - decarbonation
    - NAD - HNAD
  3. 5 carbons
    - decarbonation
    - ADP+Pi- ATP
    - 2NAD-2HNAD
    - FAD-HFAD

Q

How many carbon dioxie is produced in the kerb cycle

A

2 co2

17
Q

what other respiratory substance other than glucose are used

A
  • lipids breakdwn ( FA + GLYCEROL)
  • amino acids
18
Q

describe the process of oxidative phosphorylation

A

1.HNAD and HFAD are converted into oxidised
2. e- paases down the carries ( deacrese in energy level)
3. energy is actively transported and hydrogen is pumed
4. H+ moves from a higher to lower concentration diffuse from inner memberance in to martix by ATP synthase
5. ATP is produced
6. H+ and oxygen combine to form water
oxygen is the final electron acceptor

19
Q

equations of aneroobic respiration in animals

A

pyruvate +HNAD- lactate +NAD

20
Q

anerobic respiration in fungi

A

pyruvate + HNAD - ETHONAL +co2 +NAD

21
Q

using a respirometer to determine oxygen consumption

A
  • calculate the rate of oxygen consumption
  • distance of the dye or the bubbles moves distance
  • radius of the tube converted into volume
  • time taken
