respiration Flashcards
ATP struture and properties
3 pi
ribose
adenine
- relased in single step and immediately
- broken and regenerated
- soluable in water
name 3 function of ATP
- active transport
- cell division
- final stage of gyclosis
- synthesis reaction
- muscle contraction
aerobic repiration eqations
glucose+oxygen=carbon dioxide + water + energy
where does glycolsis occurs
cytoplasm
where does link reaction occurs
martix of the mitrochondria
where does kerb’s cycle occuurs
matrix of the mitrochondria
where does oxidative phosphorlyation occurs
- cristea
- folded inner memberane of the mitrondria
describe the process of glyclosis
- glucose converted in to x2 triose phosphate
- 2 ( ATP- ADP+pi) - converted in to 2 pyravates
- 2 NAD to HNAD
-4(ADP+pi-ATP)
why 2 ATP molecules are used to phosphorylate glucose
to make it more reactive
how pyuravte movef from the cytoplasm to mitrochndria
actively transported only for aerobic respiration
- for anerobic respriation it remains in cytoplasms if oxygen is not available
describe the process of link reaction
- pyruvates converted to acetate(2 carbons)
- carbonation
- NAD-HNAD - acetate is added to coenzyme A, so a conveted Acetyl CoA
How many ATP produced in the link reaction?
no ATP produces
how many ATP is produced from a glycolosis reactions
si the nett of 4 but 2 ATP are used so 2 are produced
describe the process of a kerb cycle
- Acetyl CoA to 6 carbons
- coenzyme is removed - 6 carbons
- decarbonation
- NAD - HNAD - 5 carbons
- decarbonation
- ADP+Pi- ATP
- 2NAD-2HNAD
- FAD-HFAD
How many ATP are poduces from the kerp cycle
1 ATP
How many carbon dioxie is produced in the kerb cycle
2 co2
what other respiratory substance other than glucose are used
- lipids breakdwn ( FA + GLYCEROL)
- amino acids
describe the process of oxidative phosphorylation
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
equations of aneroobic respiration in animals
pyruvate +HNAD- lactate +NAD
anerobic respiration in fungi
pyruvate + HNAD - ETHONAL +co2 +NAD
using a respirometer to determine oxygen consumption
- calculate the rate of oxygen consumption
- distance of the dye or the bubbles moves distance
- radius of the tube converted into volume
- time taken
