Explain the process of aerobic respiration in mitochondria of a cell and anaerobic respiration in yeast and muscle cells with the help of word equations?
Verified Answer
Explain the process of aerobic respiration in mitochondria of a cell a...
Aerobic respiration in mitochondria of a cell occurs when oxygen is present and involves the breakdown of glucose to produce ATP, water, and carbon dioxide. The process can be described by the following word equation:
Glucose + Oxygen → ATP + Water + Carbon Dioxide
Anaerobic respiration in yeast and muscle cells occurs when oxygen is not present and involves the breakdown of glucose to produce ATP, ethanol, and carbon dioxide. The process can be described by the following word equation:
Glucose → ATP + Ethanol + Carbon Dioxide
In both cases, the breakdown of glucose is facilitated by enzymes and results in the production of ATP, which is used as a source of energy by the cell. However, the presence or absence of oxygen affects the products of the reaction, with aerobic respiration producing water and anaerobic respiration producing ethanol.

Aerobic Respiration in Mitochondria
Aerobic respiration is a cellular process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. It occurs in the mitochondria of cells and consists of three main stages:
- Glycolysis
- Krebs Cycle
- Electron Transport Chain
Glycolysis
Glycolysis is the first stage of aerobic respiration, which takes place in the cytoplasm of the cell. During glycolysis, glucose is broken down into two molecules of pyruvate. This process releases a small amount of energy in the form of ATP and NADH.
Glucose + 2 ATP + 2 NAD+ → 2 Pyruvate + 4 ATP + 2 NADH
Krebs Cycle
The Krebs cycle is the second stage of aerobic respiration, which occurs in the mitochondria. During the Krebs cycle, pyruvate is converted into acetyl-CoA, which enters the cycle. The cycle produces ATP, NADH, and FADH2, which will be used later in the electron transport chain.
Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 2 H2O → CoA-SH + 3 NADH + FADH2 + GTP + 2 CO2
Electron Transport Chain
The electron transport chain is the final stage of aerobic respiration, which takes place in the mitochondria. During this stage, the NADH and FADH2 produced in glycolysis and the Krebs cycle donate their electrons to a series of protein complexes, which generate a proton gradient across the mitochondrial membrane. This gradient drives the synthesis of ATP from ADP and Pi.
NADH + FADH2 + O2 → NAD+ + FAD + H2O + ATP
Anaerobic Respiration in Yeast and Muscle Cells
Anaerobic respiration is a cellular process by which cells convert glucose into energy in the absence of oxygen. It occurs in yeast and muscle cells and consists of two main stages:
- Glycolysis
- Fermentation
Glycolysis
Glycolysis is the first stage of anaerobic respiration, which takes place in the cytoplasm of the cell. During glycolysis, glucose is broken down into two molecules of pyruvate. This process releases a small amount of energy in the form of ATP and NADH.
Glucose + 2 ATP + 2 NAD+ → 2 Pyruvate + 4 ATP + 2 NADH
Fermentation
The fermentation is the second stage of anaerobic respiration, which occurs in the absence of oxygen. During fermentation, pyruvate is converted into either ethanol or lactate, depending
