Study Notes

Meiosis and Mitosis

Meiosis generates gametes for sexual reproduction, introducing genetic variability.
Mitosis is crucial for growth, tissue repair, and asexual reproduction by producing identical daughter cells.

Fermentation and Aerobic Respiration

Aerobic respiration uses oxygen as the final electron acceptor, producing ATP effectively through the electron transport chain.
Fermentation regenerates NAD+ from NADH in the absence of oxygen, allowing glycolysis to continue.

Benefits of Fermentation

Enhances food flavors, preserves food, and provides health benefits like improved gut health.
Fermented foods are rich in probiotics, increasing vitamin and mineral bioavailability.

Risks of Fermentation

Consuming fermented products may increase gastric cancer risk, particularly with high intake of fermented soy.
Fermentation is susceptible to contamination, as seen in past botulism outbreaks linked to improperly prepared foods.

Advantages of Aerobic Respiration

Improves cognitive skills due to the memorization of exercise steps.
Boosts endurance, effectively burning calories and enhancing fitness during high-energy workouts.

Disadvantages of Aerobic Respiration

High-impact aerobics can lead to joint and bone issues.
Excessive aerobic activity may result in undesirable body shape, leading to a leaner but less curvy appearance.
Social settings like classes may deter individuals uncomfortable in group environments.

Cell Membrane Structure and Function

The cell membrane contains a phospholipid bilayer providing structural support and a barrier to protect the cell.
Phospholipids facilitate the transport of molecules like water, oxygen, and carbon dioxide.

Cholesterol in Cell Membranes

Cholesterol helps regulate membrane fluidity and prevents crystallization by separating phospholipid tails.
It secures peripheral proteins and regulates permeability to water-soluble molecules.

Membrane Proteins

Integral membrane proteins come in various structures, including α-helices and β-sheets.
Functions include:
- Junctions: Connect and join cells.
- Enzymatic activity: Speed up chemical reactions.
- Transport/channel: Facilitate diffusion and active transport.
- Recognition: Glycoproteins identify the body's own cells.
- Anchorage: Serve as attachment points for the cytoskeleton and extracellular matrix.
