Question 31
How are photosynthesis and respiration related to each other?
Assertion: Glycolysis occurs in cytoplasm.
Reason: Enzymes for glycolysis are found in cytoplasm. It is common in both aerobic/anaerobic respiration.
What is the cell cycle control system?
Respiration is a:
Catabolic and exergonic process
Anabolic and endergonic process
Anabolic and exergonic process
Catabolic and endergonic process
It is said to be protoplasmic respiration when the respiratory substrate is __________.
- Amount of O2 evolved increases as CO2 in water is absorbed by sodium bicarbonate.
- Amount of oxygen evolved decreases as carbon dioxide in water is absorbed by sodium bicarbonate.
- Amount of oxygen evolved increases as the availability of CO2 increases.
- Amount of oxygen evolved decreases as the availability of carbon dioxide increases.
- A decrease in the supply of oxygen
- Minor wear and tear of muscle fibers
- The depletion of glucose
- The accumulation of lactic acid
Question 42.1
A process is occurring throughout the day, in 'X' organism. Cells are participating in this process. During this process ATP, CO2 amd water are evolved, It is not a light dependent process.
(a) Name the process.
(b) Is it a catabolic or an anabolic process?
(c) What could be the raw material of this process?
Plants require water for their survival. But when watered excessively, plants die. Discuss.
Which of the following organisms carries out cellular respiration?
a corn plant
a yeast
a bacterium
all of the above
- Breaking of C–C bonds of complex organic molecules by oxidation in cells leading to the release of a lot of energy is called cellular respiration
- Initial stage of cellular respiration takes place in cytoplasm
Incomplete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms leaves three molecules of CO2
- TCA cycle starts with the condensation of acetyl group with OAA and H2O to yield citric acid

Assertion: Each molecule of ribulose-1, 5-bisphosphate fixes one molecule of CO2.
Reason: Three molecules of NADPH and two ATP are required for fixation of one molecule of CO2.
