NAD+ is
|
|
A vitamin
|
|
|
The reduced form of a oenzyme required for glycolysis
|
|
|
Oxidized form of a coenzyme required for the Kreb’s cycle
|
|
|
All of the above
|
Explanation:
Detailed explanation-1: -So the correct option is ‘Acceptor of hydrogen ion and electrons’.
Detailed explanation-2: -The cofactor is, therefore, found in two forms in cells: NAD+ is an oxidizing agent, accepting electrons from other molecules and becoming reduced; with H+, this reaction forms NADH, which can be used as a reducing agent to donate electrons.
Detailed explanation-3: -Steps in the Krebs Cycle Isocitrate is oxidized and decarboxylation occurs with a carbon dioxide molecule released. The coenzyme NAD+ is reduced to form another dinucleotide, NADH.
Detailed explanation-4: -NAD+ is a coenzyme involved in redox reactions during metabolism, transferring electrons from one reaction to another.
