Embibe Experts Solutions for Chapter: Respiration in Plants, Exercise 1: TS EAMCET - 10 August 2021 Shift 1

Assertion (A): When electrons move through the transport chain, protons are transported across the membrane.

Reason (R) : Because the primary acceptor of electron located towards the outside of the membrane, transfers its electrons to a H carrier (PQ). 

The correct option among the following is:

Identify the substrate level phosphorylation reactions among the following
A) Triose bis Phosphate to triose phosphate
B) Phosphoglycerate to Phosphoenol pyruvate
C) Succinyl CoA to Succinic acid
D) Malic acid to $\mathrm{OAA}$

Identify the biomolecule common to respiration involving fat, carbohydrate and protein.

Identify the wrong statements.
A) Cytochrome $\mathrm{C}$ is a small protein attached to inner surface of the outer membrane
B) Electrons from complex I are transferred to ubiquinone located within the inner membrane
C) The temperature optimum for photosynthesis of different plants does not depend on the habitat that they are adapted to.
D) There is no linear relationship between incident light and ${\mathrm{CO}}_2$ fixation rates at low light intensities.

Match the following lists.

The correct match is:

Which of the following reactions does not occur in the TCA cycle?
A) Reaction of pyruvic acid with OAA and form citric acid
B) Formation of two ${\mathrm{CO}}_2$ molecules
C) Release of $4$ molecules ${\mathrm{NADH}}^{+}+{\mathrm{H}}^{+}$
D) Formation of one GTP molecule

Find out in which of the following enzymatic reactions, $\mathrm{NADH}$ is converted to $\mathrm{NAD}$.
(A) Acetaldehyde $\to$ Ethanol
(B) Glyceraldehyde $3-$ Phosphate $\to 3$ - phosphoglyceric acid
(C) Pyruvic acid $\to$ lactic acid
(D) Oxalosuccinic acid $\to \alpha -$ketoglutaric acid
(E) $\alpha -$ketoglutaric acid $\to$ succinyl $\mathrm{CoA}$

Muscle fatigue is caused due to accumulation of this substance in the muscle
