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.
