Document Summary

Glycolysis, citric acid cycle/krebs cycle, oxidative phosphorylation. C 6 h 12 o 6 + 6 o 2 6 co 2 + 6 h 2 o + energy (atp + heat) A small amount of atp is formed in glycolysis and the citric acid cycle by substrate-level phosphorylation. Substrate level phosphorylation - involves enzymes and substrates. The process that generates almost 90% of the atp is called oxidative phosphorylation because it is powered by redox reactions. Accumulation of protons on one side of a membrane. Glycolysis ( sugar splitting ) breaks down glucose into 2 molecules of pyruvate. Glycolysis occurs in the cytoplasm and has 2 major phases. Glycolysis occurs whether or not o2 is present. Glycolysis is found in nearly all living organisms.

Related Questions

Which of the following accurately describe difference(s) between oxidative phosphorylation and substrate-level phosphorylation during aerobic respiration in eukaryotes?

	a.	Oxidative phosphorylation relies on energy initially derived from redox reactions to power ATP synthase, and substrate-level phosphorylation relies on enzymatic reactions to phosphorylate ADP.
	b.	Oxidative phosphorylation takes place in the inner mitochondrial membrane and substrate-level phosphorylation only occurs in the cytosol.
	c.	Oxidative phosphorylation uses oxygen as a substrate and substrate-level phosphorylation uses phosphate.
	d.	Oxidative phosphorylation takes place during glycolysis and the electron transport chain and substrate-level phosphorylation occurs during the citric acid cycle and chemiosmosis.
	e.	Oxidative phosphorylation produces less ATP than substrate-level phosphorylation.

Consider the process of ATP synthesis via aerobic cellular respiration.

In a series of bullet point lists, provide the following information for each of the step in aerobiccellular respiration:
Inputs, Outputs, Energy stored or generated (if it is ATP is it by substrate level phosphorylation or oxidative phosphorylation) and where within a eukaryotic cell the process is located (specifically).

I will be looking for the items listed above in the bullet points you create for each step of aerobiccellular respiration (glycolysis, transition reaction (pyruvate to acetyl-CoA), Citric Acid Cycle, Electron Transport Chain and ATPsynthase).

I don't need paragraphs, just bullet point lists showing what is what.
