can you do the same for glycolysis: Location of activity: cytoplasm
Energy source: glucose (glycogen)
Uses oxygen: anaerobic (without oxygen)
Duration: 15 seconds – 3 minutes (45 second hockey shift)
By-products: lactic acid
Advantages: quick surge of power
Limitations: buildup of H ions causes pain/fatigue
Muscle fibre type: type IIA (fast – twitch)
Can you do the same for glycolysis?
- Location of activity: Glycolysis takes place in the cytoplasm of the cell.
- Energy source: The primary energy source for glycolysis is glucose. In some cases, glycogen can also be broken down into glucose molecules and used as a fuel source.
- Uses oxygen: Glycolysis can occur both aerobic (with oxygen) and anaerobic (without oxygen). In the absence of oxygen, the process is referred to as anaerobic glycolysis.
- Duration: Glycolysis can provide energy quickly and is capable of sustaining activity for a short duration. It typically occurs within a time frame of 15 seconds to 3 minutes, which is similar to the duration of a 45-second hockey shift.
- By-products: One of the by-products of anaerobic glycolysis is lactic acid. Lactic acid accumulation can result in muscle fatigue and is associated with the burning sensation experienced during intense exercise.
- Advantages: Glycolysis allows for a rapid production of energy, providing a quick surge of power when needed. It does not rely on oxygen availability, making it a valuable energy source in situations where oxygen supply is limited.
- Limitations: The build-up of hydrogen ions (H+) during anaerobic glycolysis can lead to a decrease in pH, causing muscle pain and fatigue. Additionally, glycolysis is less efficient in terms of energy production compared to oxidative metabolism.
- Muscle fibre type: Glycolysis primarily occurs in muscle fibers classified as type IIA, which are fast-twitch fibers. These fibers have a higher glycolytic capacity and are suited for short bursts of intense activity.
