name of the metabolic step: glycolysis, pyruvate oxidation (prep - step), citric acid cycle (krebs cycle), oxidative phosphorylation: electron transport chain, oxidative phosphorylation: chemiosmosis
location in the cell: cytoplasm, mitochondrial matrix, mitochondrial matrix, inner mitochondrial membrane or inter - membrane space
molecules entering the metabolic step: 1 glucose, 2 pyruvates (processed one by one), acetyl - coa
products produced in the metabolic step: 2 pyruvates, 2 acetyl - coa, oxaloacetate, electron (e - ) carrier molecules produced: 2 nadh, 1 nadh, 3 nadh 1 fadh₂, atp molecules produced: 2 atp, 0 atp, 1 atp, oxygen requirement/use: o₂ not required, o₂ required indirectly, o₂ required directly or o₂ not required

Explanation:

Cellular respiration consists of several metabolic steps. Glycolysis occurs in the cytoplasm, starting with 1 glucose molecule and producing 2 pyruvates, 2 NADH, and 2 ATP. Pyruvate oxidation in the mitochondrial matrix converts 2 pyruvates (after processing one - by - one) into 2 Acetyl - CoA and 2 NADH. The Citric Acid Cycle (Krebs Cycle) in the mitochondrial matrix uses Acetyl - CoA, producing oxaloacetate, 3 NADH, 1 FADH₂, and 1 ATP per cycle turn. Oxidative phosphorylation involves the electron transport chain and chemiosmosis. The electron transport chain uses electron carriers (NADH and FADH₂) and oxygen is required directly or indirectly for the process to generate a large amount of ATP through chemiosmosis.

Answer:

Name of the metabolic step	Location in the cell	Molecules entering the metabolic step	Products produced in the metabolic step	Electron (e⁻) carrier molecules produced	ATP molecules produced	Oxygen requirement/use
Pyruvate Oxidation (prep - step)	Mitochondrial matrix	2 pyruvates (processed one - by - one)	2 Acetyl - CoA	2 NADH	0 ATP	O₂ required indirectly
Citric Acid Cycle (Krebs Cycle)	Mitochondrial matrix	Acetyl - CoA	Oxaloacetate	3 NADH, 1 FADH₂	1 ATP	O₂ required indirectly
Oxidative Phosphorylation: Electron Transport Chain	Inner mitochondrial membrane or inter - membrane space	NADH, FADH₂	-	-	-	O₂ required directly
Oxidative Phosphorylation: Chemiosmosis	Inner mitochondrial membrane or inter - membrane space	-	-	-	Large amount of ATP	O₂ required directly
