(a) Where does it takes place ?
(b) When and by whom it was discovered ?
(c ) Name the first formed product of the cycle.
(d) How many ATP molecules are generated per cycle ?
(e ) TCA cycle is a amphibolic pathway. Say yes or no. Why ?

Text Solution

Verified by Experts

(a) TCA cycle takes place in mitochondrion.
(b) TCA cycle was discovered by Sir Hans Adolf Krebs in 1937.
(c ) The first formed product of TCA cycle is citric acid or citrate.
(d) Only one ATP molecule is generated per TCA cycle.
(e ) Yes. TCA is an amphibolic pathway because it involves both anaerobic and catabolic reactions.
