what is required for glycolysis to continue?

its products of pyruvate and H must be constantly removed .

H must be released from reduced NAD in order to regenerate NAD.

what are te two types of anaerobic respiration in eukaryotic cells?

-in plants and microorganisms e.g.yeast, pyruvate--> ethanol and CO2

-in animals, pyruvate--> lactate

what happens in the production of ethanol in plants and some miroorganisms?

the pyruvate molecule formed in glycolysis loses a CO2 molecule and accepts hydorgen form reduced NAD to produce ethanol.

whats the overall equation for production of ethanol in plants and microorganisms?

pyruvate+reduced NAD-->CO2+ethanol+NAD

what do humans use anaerobic respiration of yeast for?

for the brewing industry for ethanol by the natural fermentation of carbohydrates such as grape in wine production or barley seeds for beer production into ethanol.

when and where does lactate in animals most commonly occur?

in muscles due to streneous exersize.

what occurs if oxygen is used up faster than it is supplied?

what must be done if muscles need to keep working and so glycolysis must coontinue?

-an oxygen debt

-pyruvate molecules produced must take up 2 H atoms from reduced NAD produced and form lactate.

what is the overall equation for production of lactate in animals?

pyruvate+reduced NAD-->NAD+lactate

lactate must be oxidised back to pyruvate. what happens to it next?

its either further oxidised to produce energy


its converted into glycogen

what are the effects of lactate if left to accumulate in muscles?

what is important in this case?

-cramping and fatigue

-that its removed by blood and converted into glycogen.

in what 2 ways is energy derived from cellular respiration?

-substrate-level phosphorylation in glycolysis&krebs cycle (direct linking o Pi to ADP)

-oxidative phosphorylation in electron transport chain(indirect) using Hatoms fromm glycolysis and krebs cycle carried by NAD&FAD. Most ATP produced this way.

what is ATP produced by anaerobic respiration formed by?

what produces more ATP aerobic or anaerobic respiration?

glycolysis. krebs cycle and electron transport chain takes no part.

Aerobic produces more than anaerobic.
