- Energy from Glucose.Glucose produced during photosynthesis contains energy absorbed from sunlight.
- GlycolysisGlucose is phosphorylated using ATP to form glucose-6- phosphate.
- PhosphorylationGlycolysis can be considered to be divided into three main steps.
- LysisHexose bisphosphate is broken down into two triose phosphate molecules.
- Substrate Level PhosphorylationSubstrate-level phosphorylation is the formation of ATP without the involvement of the electron transport chain.
- The Link ReactionPyruvate enters the mitochondria.
- The Krebs Cycle.The Krebs cycle also occurs in the matrix of the mitochondria.
- oxidative phosphorylationThe electron transport chain (ETC) is a group of protein complexes and mobile electron carriers in the inner mitochondrial membrane.
- ATP SynthaseThe production of ATP from ADP and inorganic phosphate using the energy from the proton gradient in the intermembrane space of the mitochondria is…

- Anaerobic Respiration - Plants and Microorganisms.For glycolysis to continue NAD must be continuously regenerated so the hydrogen and electron must be released from reduced NAD i.e. reduced NAD must…
- Anaerobic Respiration - MammalsAnimals respire anaerobically as a means of overcoming a temporary shortage of oxygen.
