Study Notes
Respiration Basics
- Glucose is the primary food source used in respiration.
- Internal respiration is governed by enzymes that facilitate energy release from glucose and produce carbon dioxide.
Energy Storage and Use
- Energy captured in molecules is known as ATP (Adenosine Triphosphate).
- ATP breaks down to supply energy for cellular processes, such as muscle movement and cell growth.
Types of Respiration
- Aerobic respiration occurs in the presence of oxygen, releasing energy from food.
- Anaerobic respiration takes place without oxygen, also releasing energy from food.
- Organisms that primarily rely on aerobic respiration are termed aerobes.
Aerobic Respiration Efficiency
- Aerobic respiration is efficient, converting about 40% of glucose's energy into ATP.
- Any energy not converted into ATP is lost as heat.
Stages of Respiration
- Stage 1: Glycolysis, occurs in the cytosol where enzymes are located.
- Glycolysis does not require energy and releases small amounts of energy.
- It converts a 6-carbon carbohydrate (glucose) into two 3-carbon molecules, maintaining stored energy within them.
- Stage 2 requires carbon dioxide (CO2) and occurs in the mitochondria, where necessary enzymes are found.
- It releases a large amount of energy.
- The 3-carbon molecules are further broken down into carbon dioxide and water during this stage.
Energy Transition and By-products
- The anaerobic breakdown of 3-carbon molecules releases a substantial amount of energy.
- Very little energy remains in the form of carbon dioxide and water after respiration.
