CELL RESPIRATION

ANAEROBIC RESPIRATION FERMENTATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Aerobic respiration:Glucose + oxygen ____ carbon dioxide + water + a lot of energyAnaerobic respiration in Yeast:Glucose ____ carbon dioxide + ethanol + a little energyStudy the equations and give two similarities between aerobic and anaerobic respiration in Yeast.
A
Both use glucose and produce carbon dioxide
B
both use oxygen and produce carbon dioxide
Explanation: 

Detailed explanation-1: -The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-2: -In both aerobic and anaerobic respiration, the food is broken down to release energy. In aerobic respiration the break down of food occurs in presence of oxygen and in anaerobic it occurs in the absence of oxygen.

Detailed explanation-3: -Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Unlike aerobic respiration, the end products here are ethyl alcohol as in yeasts and lactic acid as in animal cells. So the answer is ‘Alcohol and lactic acid’.

Detailed explanation-4: -Aerobic respiration releases a greater amount of energy compared to anaerobic respiration.
