Question 1
1 / -0

The enzyme that is not found in a $$C_{3}$$ plant is

A
RuBP Carboxylase

B
PEP Carboxylase

C
NADP reductase

D
ATP synthase

Solution

PhosphoEnolPyruvate (PEP) carboxylase is present in the mesophyll cells of the $$C_4$$ plants and catalyse the conversion PEP to OxaloAecetate. (OAA), the first 4C stable compound formed in $$C_4$$ plants formed by the acceptance of atmospheric $$CO_2$$ by PEP in presence of PEP carboxylase.
So, the correct answer is 'PEP Carboxylase'
Question 2
1 / -0

Value of R.Q. in succulents is ____________.

A
Unity

B
Infinite

C
Less than unity

D
Zero

Solution

Succulents do not evolve carbon dioxide during the night (when their stomata are open) as the same is in carbon fixation. They also change carbohydrates to organic acids which utilise oxygen but do not evolve carbon dioxide.

$${2C}_{6}{H}_{12}{O}_{6}+{3O}_{2}\longrightarrow\underset {Malic \,acid}{{3C}_{4}{H}_{6}{O}_{5}}+{3H}_{2}O$$
$$R.Q.=\frac{Zero\,{CO}_{2}}{{3O}_{2}}=Zero$$
So the correct option is D.
Question 3
1 / -0

If volume of $${CO}_{2}$$ liberated during respiration is more than the volume of $${O}_{2}$$ used, then the respiratory substrate will be

A
Carbohydrate

B
Fat

C
Protein

D
Organic acid

Solution

RQ slightly more than unity is found when organic acids are broken down as respiratory substrates under aerobic conditions, e.g. for the breakdown of oxalic acid liberation of $$CO_2$$ is more than $$O_2$$.
$$RQ=\frac{4{CO}_{2}}{{O}_{2}}=4.0$$.
So the correct option is D.
Question 4
1 / -0

Refer the given figure showing citric acid cycle. What changes take place during the conversion of A to B?

A
$$CO_2$$ is liberated

B
$$NAD^+$$ is converted to $$NADH$$ + $$H^+$$

C
GTP is formed from GDP

D
All of these
Question 5
1 / -0

Select the correct option:
Refer to the following flow chart representing the cellular respiration and its fuels. Blanks 1,2,3,4,5,6 and 7 are respectively

A
amino acids, carbohydrate, glucose, fats, glycerol, fatty acid, acetyl Co-A.

B
fats, acetyl Co-A, amino acid, fatty acid, carbohydrate, glycerol, glucose.

C
fatty acid, glucose, acetyl Co-A, glycerol, fats carbohydrate, amino acid.

D
carbohydrate, fats, glycerol, fatty acids, amino acid, glucose, acetyl Co-A.

Solution

1 - Amino acids
2 - Carbohydrate
3 - Glucose
4 - Fats
5 - Glycerol
6 - Fatty acid
7 - Acetyl Co-A
So, the correct answer is (a).
Question 6
1 / -0

Respiratory quotient is defined as

A
$$O_2$$ evolved / $$CO_2$$ absorbed

B
$$CO_2$$ evolved / $$O_2$$ absorbed

C
$$CO_2$$ evolved

D
$$CO_2$$ absorbed/ $$O_2$$ evolved.

Solution

The respiratory quotient can be defined as the ratio of the CO2 evolved to the O2 absorbed this could be calculated for a cell, a tissue, or even an organism.
So, the correct answer is 'CO2 evolved / O2 absorbed'.
Question 7
1 / -0

Refer to the given figure and select the correct option for A,B,C and D.

A
A-Fats ; B- Proteins;C-3-PGAL ; D- AcetylCoA

B
A-Fats ; B- Proteins;C-3-PGAL ;D-$$CO_2$$

C
A-Proteins ; B- Fats ; C- Acetyl CoA ; D- PEP

D
A-Proteins ; B- Fats ; C - PEP ;D - Acetyl CoA

Solution

In the given image a represents fat, b represent proteins, c represents 3 phosphoglyceraldehydes while d- acetyl CoA.
So, the correct option is 'A-Fats ; B- Proteins;C-3-PGAL ; D- AcetylCoA'.

Question 8

1 / -0

Match column I with column II and select the correct option from the codes given below.

Column I	Column II
A. Krebs' cycle	(i) Inspiration
B. Lungs	(ii) Hamburger's phenomenon
C. Diaphragm	(iii) Diffusion of $$CI^{-}$$ into RBCs
D. Pons varolii	(iv) Mitochondria
E. Chloride shift	(v) Crural and costal
	(vi) Pneumotaxic centre
	(vii) Expiration

A-(iv), B-(i), (vii), C-(v), D-(vi), E-(ii), (iii)

A-(v), B-(i), C-(iv), (vii), D-(vi), E-(ii), (iii)

A-(ii), (vi), B-(i), C-(iii), D-(v), (vii), E-(iv)

A-(iii), B-(i), C-(ii), (v), D-(vi), (vii), E-(iv)

Question 9
1 / -0

Which of the following options contains the end products formed during anaerobic respiration in Yeast?

A
$$H_2O, CO_2$$ and energy

B
$$H_2S, C_6H_{12}O_6$$ and energy

C
$$CO_2, C_2H_5OH$$ and energy

D
$$H_2O$$ and $$CO_2$$
Question 10
1 / -0

In some biochemical reaction, two redox equivalents in the form of hydrogen atoms come out from PGAL and transferred to NAD$$^+$$, site of this process is

A
Stroma of chloroplast

B
Cytoplasm

C
Mitochondrial matrix

D
Outer membrane of mitochondria

Solution

The given reaction is one of the step of glycolysis. Glycolysis takes place in the cytoplasm of the cell. Two redox-equivalents in the form of two hydrogen atoms come out from PGAL (phosphoglyceraldehyde) and transferred to a molecule of NAD$$^+$$. In this, PGAL is oxidized with inorganic phosphate to get form BPGA (biphosphoglyceric acid) and NADH$$_2$$ is formed.
Thus, the correct answer is 'Cytoplasm'.
