  • During deficiency of oxygen in tissues of human beings, pyruvic acid is converted into lactic acid in the (a) cytoplasm (b) chloroplast (c) mitochondria (d) golgi body

During deficiency of oxygen in tissues of human beings, pyruvic acid is converted into lactic acid in the
(a) cytoplasm
(b) chloroplast
(c) mitochondria
(d) Golgi bodies

Answers (1)

The pyruvate formed from glycolysis goes into Kreb's cycle as an acetyl co-enzyme and creates a pool of chemical energy (ATP, NADH, and FADH2). One of the substitute destinies of pyruvic acid in cellular respiration is that it can be changed over into lactic acid. This regularly happens in the cytoplasm of solid tissue under exhausting conditions. Hence Pyruvic acid is converted into lactic acid in the cytoplasm of muscle cells during deficiency of oxygen in human beings. Hence, (c) is the correct option.
