Is the process of forming ATP digestion, cellular respiration, metabolism, or nutrition?
1 Answer
Cellular respiration.
Explanation:
ATP is the energy carrier of the cell that fuels most of the cellular processes. Making ATP happens at a cellular level . Digestion, metabolism and nutrition are terms that usually refer to processes in body systems e.g. digestive system.
There are three phases of cellular respiration:
- Glycolysis
- Krebs cycle
- Electron tranport chain
During glycolysis glucose is broken down in several steps. The net production in this process is 2 ATP .
In the Krebs cycle (also called Citric Acid Cycle) 2 ATP is produced, but more importantly electrons are released and transferred to a carrier molecule (NAD+ or FADH).
The electrons from the Krebs cycle are used by the electron transport chain: a series of proteins in the mitochondrial membrane. The proteins use the electrons to pump hydrogen ions (H+) across the mitochondrial membrane. The energy released when these H+ ions flow back through a specific protein (ATP synthase) is used to produce 32 ATP.
