Read the following statements and select the correct option :
(A) Alcoholic fermentation occurs in muscles due to inadequate oxygen.
(B) Lactic acid fermentation involves removal of hydrogen from pyruvate.
(C) The main purpose of fermentation is to increase ATP production beyond glycolysis.
(D) Alcoholic fermentation and lactic acid fermentation both start with glycolysis.
Match the List-I with List-II and select correct answer:-
A-v, B-ii, C-i, D-iii, E- iv
A-v, B-i, C-ii, D-iv, E-iii
A-v, B-iv, C-iii, D-ii, E-i
Statement 1 : During oxidative decarboxylation of one molecule of pyruvic acid in mitochondrial matrix one molecule of NADH+H⁺ is produced.
Statement II : In glycolysis, glucose undergoes partial oxidation to form four molecule of pyruvic acid.
Match the following columns.
Column-I Column-II
(A) Glucose (I) Can enter fermentation as well as Krebs’ cycle depending upon cellular need
(B) Fats (II) Favoured substrate for respiration
(C) Proteins (III) Have RQ below 1
(D) Pyruvic acid (IV) Will degrade into amino acids for respiration
Choose the most appropriate answer from the options given below
Statement-I : Proton concentration becomes higher in the intermembrane space than in the mitochondrial matrix during electron transport.
Statement-II : The electron transport chain synthesizes ATP by substrate level phosphorylation.
