The correct sequence of electron acceptor in ATP synthesis is:
1 cyt $a$ a b c
2 cyt $bca{{a}_{3}}$
3 cyt $bc{{a}_{3}}a$
4 cyt $cba{{a}_{3}}$
Explanation:
(b) The correct sequence of electron acceptor in ATP synthesis is cyt $b$ c a ${{a}_{3}}$. These are arranged in order of their increasing redox potential and electron flow through the chain in step wise manner from the more electronegative compound to the more electropositive ${{\text{O}}_{2}}$. On the basis of redox potential cytochrome 75. (d) acceptor order is cyt $bc$ a ${{a}_{3}}$.

The overall goal of glycolysis, Kreb's cycle and the electron transport system is
the formation of:
1 ATP in one large oxidation reaction
2 sugars
3 nucleic acids
4 ATP in small stepwise units
Explanation:
(d) Krebs' cycle is the process by which living cells break down organic molecules in the presence of oxygen to produce the energy they need to grow and divide. It cycle involves decarboxylation steps.

Which of the following is incorrect regarding the Kreb's cycle?
1 Itis also known as tricarboxylic acid cycle.
2 It occurs in mitochondria.
3 It starts withsix carbon compound.
4 It does not involve any decarboxylation step.
Explanation:
(c) ETS (Electron transport system or chain) is a series of coenzymes that takes part in the passage of electrons from a chemical to its ultimate acceptor. ETS is present in the inner mitochondrial membrane, oxidation of one molecule of NADH gives rise to 3 molecules of ATP, while that of one molecule of FADH $_{2}$ produces 2 molecules of ATP. In respiration, energy of oxidation - reduction is utilized for the production of proton gradient.
