Study Notes
Energy and ATP
- Exergonic reactions are a type of reaction that releases energy from the system.
DNA Replication
- The main function of DNA polymerase is to synthesize new DNA strands by adding nucleotides to a template.
ATP Structure
- ATP (Adenosine Triphosphate) is composed of adenine, ribose, and three phosphate groups.
ATP Hydrolysis
- Hydrolysis of ATP with water releases 30.5 kJ of energy per mole of ATP.
Energy Production
- The process by which photosynthesis and/or respiration provide the energy required to synthesize ATP is called energy coupling.
ATP Function
- The main function of ATP hydrolysis in the cell is to provide energy for various cellular processes.
Photosynthesis
- Photoautotrophs are organisms that use light energy, carbon, and water to produce organic molecules through photosynthesis.
Electron Carriers
- The main function of NAD+/NADH in cellular respiration is to facilitate electron transport and generate ATP.
Aerobic Respiration
- The products of aerobic respiration of glucose are carbon dioxide, water, and ATP.
Redox Reactions
- The main function of oxidation and reduction in living systems is to facilitate energy transfer and storage.
