Question

cellular respiration - fill in the table below. then use the information from the table to fill in the diagram.
name of the metabolic step: glycolysis, pyruvate oxidation (pre - 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, inner - mitochondrial matrix or inter - membrane space
molecules entering the metabolic step: 1 glucose, 2 pyruvates, 2 pyruvates (processed one by one), acetyl - coa
products produced in the metabolic step: 2 pyruvates, 2 acetyl - coa, oxaloacetate, 2 nadh, 2 nadh, 3 nadh 1 fadh2, 1 atp, 0 atp, 2 atp
electron (e - ) carrier molecules produced: 2 nadh, 2 nadh, 3 nadh 1 fadh2
atp molecules produced: 2 atp, 0 atp, 1 atp
oxygen requirement/use: o2 not required, o2 indirectly required, o2 indirectly required, o2 directly required, o2 directly required

Explanation:

Glycolysis occurs in the cytoplasm. One glucose molecule is the starting - material. It produces 2 pyruvates, 2 NADH, 2 ATP, and oxygen is not required. Pyruvate oxidation occurs in the mitochondrial matrix. 2 pyruvates are processed one - by - one to produce 2 Acetyl - CoA and 2 NADH, and oxygen is indirectly required. The citric acid cycle (Krebs cycle) also occurs in the mitochondrial matrix. Acetyl - CoA enters, and the cycle produces oxaloacetate, 3 NADH, 1 FADH₂, 1 ATP, and oxygen is indirectly required. Oxidative phosphorylation involves the electron transport chain in the inner - mitochondrial membrane and chemiosmosis. Oxygen is directly required for the electron transport chain to function as the final electron acceptor.

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 indirectly required
Citric Acid Cycle (Krebs Cycle)	Mitochondrial matrix	Acetyl - CoA	Oxaloacetate, 3 NADH, 1 FADH₂, 1 ATP	-	1 ATP	O₂ indirectly required
Oxidative Phosphorylation: Electron Transport Chain	Inner - mitochondrial membrane	-	-	-	-	O₂ directly required
Oxidative Phosphorylation: Chemiosmosis	Inner - mitochondrial membrane/Inter - membrane space	-	-	-	-	O₂ directly required
