occurs without oxygen and produces a large amount of ATP.
|
|
|
requires no oxygen and produces a minimal amount of ATP through glycolysis
|
Detailed explanation-1: -Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
Detailed explanation-2: -Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.
Detailed explanation-3: -Glycolysis: In the absence of oxygen, cells generate ATP through glycolysis, which is a common process in both aerobic and anaerobic respiration.
Detailed explanation-4: -Summary. Fermentation makes ATP without oxygen, which involves glycolysis only. Fermentation recycles NAD+, and produces 2 ATPs. In lactic acid fermentation, pyruvate from glycolysis changes to lactic acid.
Detailed explanation-5: -Fermentation begins with glycolysis which breaks down glucose into two pyruvate molecules and produces two ATP (net) and two NADH. Fermentation allows glucose to be continuously broken down to make ATP due to the recycling of NADH to NAD+.
