Helpppp!!!
1) Summarize the roles of the Krebs cycle and the electron transport chain during aerobic respiration.
2) Describe the role of fermentation in the second stage of cellular respiration.
1. The role of both the Krebs Cycle and the electron transport chain is to produce ATP
2. alcoholic fermentation uses enzymes to change the glucose to ethyl alcohol. it also created co2.
unless you want lactic acid fermentation? its when your body cannot get enough oxygen to your muscles (usually during hard exercise), so your muscles produce lactic acid when producing ATP.
both are anaerobic. don't require oxygen.
