Q. No.Plants can get along without respiratory organs because of all the following except:
1. Each plant part takes care of its own gas exchange needs
2. Plants do not present great demands for gas exchange.
3. Gas diffusion in plants occurs easily over long distances in plants
4. Each living cell in a plant is located quite close to the surface of plant
The co-factor required for the activity of pyruvate dehydrogenase is:
1. Zinc
2. Magnesium
3. Manganese
4. Copper
For each ATP produced, how many H pass through F0 from the intermembrane space to the matrix down the electrochemical proton gradient?
1. 1
2. 2
3. 3
4. 4
If fatty acids were to be respired, they would first be degraded to:
1. Glucose-6 phosphate
2. Pyruvate
3. Acetyl-CoA
4. Alpha ketoglutarate
When proteins are used as respiratory substrates, the respiratory quotient would be about:
1. 1.2
2. 1.0
3. 0.9

The energy which is required for life processes is obtained by
A. Hydrolysis of Macromolecules
B. Hydrolysis of food
C. Oxidation of Macromolecules
D. Carboxylation of Macromolecules
Which of the following is not true?
(1) All the energy required for life processes is obtained by oxidation of some macromolecules that we call food
(2) Only green plants and cyanobacteria can prepare their own food
(3) The result of the photosynthesis is such that the light energy is trapped in the form of mechanical energy
(4) Not all the cells, tissues and organs photosynthesise in green plants
The following statements are true except
(1) All the food that is respired for the life processes comes from photosynthesise
(2) Carnivores depend indirectly on plants for their food
(3) Saprophytes depend on dead and decaying matter
(4) Respiration is a metabolic process occurs intercellular spaces
Respiration is
(1) Breaking of a type of bonds like ionic or non ionic of complex compounds through oxidation within the cell by utilizing bulk of energy
(2) Breaking of C-C bonds of simple molecules through hydrolysis within the cell by releasing energy
(3) Breaking of C-C bonds of complex molecules through oxidation within the cell to release considerable amount of energy
(4) Breaking of C-C bonds of complex molecules through hydrolysis within the cell by releasing energy
Respiratory substrate are the compounds
(1) Which get oxidized during Respiration
(2) Which get hydrolysed during Respiration
(3) Which get reduced during Respiration
(4) Which catalyze the process of Respiration
