Q

anaerobic respiration in the muscles during exercise

A
  • muscles don’t get enough oxygen
  • therefore respire anaerobically - glycolysis
  • gl. broken down - pyruvic acid formed
  • little energy released
  • p-acid becomes lactic acid (lactic acid fermentation)

Q

Krebs Cycle

A
  • aerobic - in mitochondrion
  • pyruvic acid enters mitochondrion
  • H atoms and CO2 are releases in cyclic reactions
  • coenzymes carry the H atoms to the 3rd phase

Q

Oxidative Phosphorylation

A
  • aerobic - in the cristae
  • H-atoms carried to H transfer system by coenzymes
  • transferred from one acceptor to next, releasing energy (E)
  • the E binds a P molecule to ADP, forms ATP
  • Oxygen: final H acceptor.
  • reacts with 2 H-atoms to form water

Q

how to make wine.

A
  • sugar in grape pulp ferments after touching yeast in air
  • pulp called must
  • yeast added - put in vats
  • sugar -> alc. and CO2
  • fermentation finishes in vats
  • filtered then ages in barrels

Q

how to make beer.

A
  • barley, water, hops, yeast
  • barley soaked until germination
  • then dried - malted barley
  • sugars dissolve in hot water; then drained into syrup aka wort
  • hops added and boiled
  • yeast added to ferment - converts gl. to alc. and CO2

Q

anaerobic respiration

A
  • absence of oxygen
  • glucose only partially broken down - releases less energy
25
Q

difference between aerobic and anaerobic respiration.

A

Anaerobic

  • absence of O2
  • produce lactic acid, CO2, ethanol
  • little energy released
  • in cytosol

Aerobic

  • presence of O2
  • produces CO2 and alc.
  • large amount of energy released
  • cytosol and mitochondrion

Q

how to bake bread.

A
  • mix flower, water, yeast, sugar into dough
  • yeast makes sugar ferment - alc. and CO2
  • dough kept warm to rise
  • put in oven to bake - alc evaporates. yeast destroyed
  • baked bread

Q

anaerobic respiration in industry

A
  • yeast and fungi can to produce alcahol
  • yeast - bread
  • some bacteria in the presence of lactose - cheese, yoghurt, sour milk
33
Q

A

mitochondrion

34
Q

test: O2 is used by living organisms during CR.

A
  • use germinating beans
  • sterilise beans, equipment with alc. (prevents bacteria growth and CR of bacteria)
  • kill some beans by boiling so CR can’t happen
  • place dead (A) and germinating (B) beans in separate tubes with stoppers
  • leave overnight
  • insert glowing splint

Results:

  • A- splint ignites; O2 is present; CR hasn’t happened
  • B- splint dies; No O2; CR has happened

O2 is used by living orgs during CR.

  • place germinating (A) and dead (B) beans in separate tubes, along with clear lime water, foam rubber
  • place in warm place overnight

Results:

  • A- water becomes milky
