Study Notes

Respiration Processes

Aerobic respiration occurs in the mitochondria and produces water, while anaerobic respiration has commercial applications.
Both aerobic and anaerobic respiration start with glycolysis, converting glucose to pyruvate.
Anaerobic respiration is utilized in the production of beer, wine, bread, yogurt, and cheese.

Cellular Respiration Equation

The equation for cellular respiration is glucose + oxygen = carbon dioxide + water, generating energy in the form of ATP.
This process contrasts with the equation where carbon dioxide and water produce glucose and oxygen, which requires light energy.

Glycolysis

Glycolysis breaks down glucose into two pyruvate molecules, producing ATP and NADH while oxidizing glucose.
During glycolysis, 2 ATP are used, and 4 ATP and 2 NADH are produced.

Citric Acid Cycle

Acetyl-CoA enters the citric acid cycle, where it combines with a 4-carbon molecule to form citric acid and regenerates the 4-carbon molecule through redox reactions.

Viruses

Viruses are classified as nonliving infectious agents, containing unique genetic material and requiring a host for replication.
The ribosome has minimal impact on a virus's ability to infect host cells, while the nucleic acid component is injected into the infected cell.

Viral Life Cycle

The lytic cycle results in the destruction of the host DNA, while the lysogenic cycle integrates viral genetic information without immediate destruction.
Both cycles hijack the host cell's metabolism, leading to viral replication.

Arguments on Viruses' Status

Support for viruses being classified as alive includes their ability to replicate within a host and possess unique genetic information, while they do not have a cell membrane or produce proteins independently.
