Answer: Through Cellular Respiration
Step-by-step explanation:
Cellular respiration takes the stored glucose and makes it into ATP which then the cell can use as energy.
1) Glycolysis: harvests chemical energy by oxidizing glucose to pyruvate.
- occurs in the cytoplasm.
- reactants: one molecule of glucose and two molecules of ATP.
- products: ATP, NAD+ reduced to NADH (electron carrier), and pyruvate.
2) Pyruvate Oxidation: conversion of pyruvate to Acetyl coenzyme A.
- occurs in the mitochondrial matrix.
- reactants: pyruvate and O2.
- products: NAD+ reduced to NADH (electron carrier), Acetyl CoA.
Citric Acid Cycle (Krebs Cycle): completes the energy-yielding oxidation of organic molecules.
- occurs in the mitochondrial matrix.
- Acetyl CoA enters the cycle.
- products: 2 ATP, NADH and FADH produced (electron carriers), and CO2 as waste.
3) Oxidative Phosphorylation: the process by which ATP synthesis is coupled to the movement of electrons through the mitochondrial electron transport chain and the associated consumption of oxygen (chemiosmosis). (sciencedirect.com)
- electron transport chain: O2 final electron acceptor.
- chemiosmosis: the process of diffusion of H+ ions across a selectively permeable membrane through the H+ gradient (proton motive force) and ATP synthase.
- reduced to H2O and 32 ATP formed.
