Study Notes
Functions and Biochemistry of ATP, Respiration, and Fermentation
- ATP functions: Stores energy for cell use and transports energy within the cell
- Respiration energy cycle: ATP releases energy, forms ADP and inorganic phosphate, and can be reassembled into ATP with available energy
- ATP formation: Third phosphate forced to join ADP, storing energy in high-energy bond
- Metabolism waste removal: Urea, carbon dioxide, and water excretion
- Respiration stages: Glycolysis, Krebs cycle, and Electron Transport Chain
- Aerobic respiration: Breakdown of sugar to release energy in the absence of oxygen, production of lactic acid
- Anaerobic respiration: Fermentation of sugars, biotechnological uses, advantages, and disadvantages
- Production of ethanol by yeast: Preparation steps, fermentation lock usage, and completion indicators
- Testing for the presence of alcohol: Iodoform test procedure and confirmation of ethanol presence
Test your knowledge of ATP functions, respiration stages, aerobic and anaerobic respiration, and the production of ethanol by yeast in this biochemistry and metabolism quiz. Explore the processes and biotechnological uses of fermentation, as well as testing methods for the presence of alcohol.
