Study Notes
Cellular Respiration Overview
- Respiration involves the inhalation and exhalation of oxygen and carbon dioxide.
- Cellular respiration occurs inside the cell, specifically within the mitochondria.
Mitochondria
- Mitochondria are organelles responsible for energy production within cells.
- Energy is produced through the conversion of glucose and oxygen into ATP, carbon dioxide, and water.
Chemical Equation
- The respiration equation can be expressed as:
- C6H12O6 + 6 O2 > 6 CO2 + 6 H2O + Energy
- This translates to: Sugar + Oxygen > Carbon Dioxide + Water + Energy.
Relationship Between Photosynthesis and Cellular Respiration
- During photosynthesis, the inputs (carbon dioxide and water) are the outputs of cellular respiration, and vice versa.
- They are essentially inverse processes.
Fermentation
- Fermentation is an anaerobic process for energy production when oxygen is scarce.
- This process yields less energy compared to cellular respiration.
- Lactic acid is produced during fermentation due to insufficient oxygen for aerobic respiration.
Energy and Work
- Energy is crucial for cellular functions and work.
- The Law of Conservation of Energy states that energy is neither created nor destroyed but converted into different forms.
Cell Membrane
- The cell membrane is semi-permeable, controlling the movement of substances in and out of the cell.
- During cellular respiration, glucose and oxygen enter cells, while carbon dioxide and water are expelled as waste products.
Types of Respiration
- Cellular respiration can occur through aerobic (with oxygen) or anaerobic (without oxygen) processes.
- Aerobic respiration is more efficient in energy production compared to anaerobic respiration.
Blood and Energy Transport
- Glucose and oxygen are transported to cells through the blood.
Additional Concepts
- Digestion is the process of breaking down food into usable forms like glucose.
- Breathing differs from cellular respiration; breathing is the physical act of gas exchange, while cellular respiration is the biochemical process of energy production.
Summary of By-products and Reactants
- Waste products of cellular respiration include carbon dioxide and water.
- Reactants necessary for cellular respiration are glucose and oxygen.
Body Adaptation
- During intense exercise when oxygen levels are low, the body adapts by switching to anaerobic respiration, leading to lactic acid fermentation.
