Compare and contrast lactic acid fermentation and ethanol fermentation (alcohol

Question

Compare and contrast lactic acid fermentation and ethanol fermentation (alcohol fermentation). Move each phrase to the appropriate category. If a phrase describes both types of fermentation, classify it as both 2 ATP O- 2 ADP2D C=O C=O CH 2 Pyruvic acid Glycolysis Glycolysis CH 2 Pyruvic acid 2co, 2 NAD 2 NADH +2 H 2 NAD 2 NADH +2 H C=O H-C-OH CH 2 Lactate CO No loss of CO H-C-OH CH 2 Ethanol C-O s lost CH 2 Acetaldehyde Ethanol fermentation Both Lactic acid fermentation considered to be an anaerobic process used by animal cells generates ethanol used by yeast cells produces lactic acid (lactate) regenerates NAD* that can be used in glycolysis

Explanation / Answer

ethanol fermentation:-

Considered to be an unaerobic process.

generates ethanol

used by yeast cells

regenerates NAD+ that can be used in glycolysis.

Lactic acid fermentation:-

Considered to be an anaerobic process.

used by animal cells

produces lactic acid

regenerates NAD+ that can be used in glycolysis.

Both:-

Considered to be an anerobic process.

regenerates NAD+ that can be used in glycolysis.
