All enzymes of TCA cycle are located in the mitochondrial matrix except one which is located in inner-mitochondrial membranes in eukaryotes and in cytosol in prokaryotes. This enzyme is

Which of the following cellular metabolic processes can occur both in the presence or absence of O₂?

Consider the first reaction of TCA cycle.

What is true about compound A?

Rise in the water level from X to Y in the given experimental set-up demonstrates

Which of the following is a 4-carbon compound?

Select the wrong statement

During complete metabolism of glucose, the number of ATP formed is

Read the given statements and select the correct option.
Statement 1: During photophosphorylation (of photosynthesis), light energy is utilised for the production of a proton gradient during ATP synthesis.
Statement 2: In respiration, the energy of oxidation-reduction is utilised for the phosphorylation and thus the process is called oxidative phosphorylation.

Electron transport chain (ETC) is a set of ______ electron carriers present in a specific sequence along ______ mitochondrial membrane.

During the process of aerobic respiration, (i) gets oxidised and its electrons get transferred to the electron transport chain while in photosynthesis, (ii) gets oxidised to transfer molecules to the electron transport chain.

Select the option that correctly fills the blanks in the following statements.
A. Glucose has (i) carbon atoms, pyruvic acid has (ii) carbon atoms and the acetyl group has (iii) carbon atoms.
B. Electrons enter the electron transport system as parts of hydrogen atoms attached to (i) and (ii).

Amount of energy released during hydrolysis of a high energy bond of ATP is

Select the correct statements.
(i) Between temperature range 0−25^∘C, rate of respiration doubles for every 10^∘C rise in temperature.
(ii) Cytochromes are iron-porphyrin compounds.
(iii) Respiratory rate of wounded or injured plant parts generally decreases.

Which of these are respiratory poisons or inhibitors of ETC?
