The first 5-C dicarboxylic acid in Kreb's cycle is
1 OAA
2 Succinic acid
3 \(\alpha\)-ketoglutaric acid
4 Acetyl coenzyme A
Explanation:
The first 5-C dicarboxylic acid in Kreb's cycle is alpha-ketoglutaric acid.
BIOXI14: RESPIRATION IN PLANTS
337774
The site of Kreb's cycle is:
1 Cytoplasm
2 Mitochondrial matrix
3 Intermembrane space of mitochondria
4 Racker's particles
Explanation:
The Kreb's cycle or tricarboxylic acid (TCA) cycle the oxidation of the acetyl group of acetyl CoA to \(\mathrm{CO}_{2}\). All enzymes of Krebs' cycle are located in the mitochondrial matrix except one, succinate dehydrogenase which is located in the inner mitochondrial membrane in eukaryotes. Thus, it takes plac in the mitochondrial matrix.

How many substrate level phosphorylations take place in one turn of TCA cycle?
1 4
2 3
3 2
4 1
Explanation:
1 substrate level phosphorylations take place in one turn of TCA cycle. During the conversion of succinyl-CoA to succinic acid a molecule of GTP is synthesised. This is a substrate level phosphorylation.
