Question

The mitochondria

Answer 1

Answer:

The correct answer are

a. Are the sites of oxidative phosphorylation.

c. Possess their own DNA and

d. Are sites of ATP production.

Explanation:

Mitochondria are double membranous structures that are found in eukaryotes. These are structure present in almost all the eukaryotes. The process of aerobic respiration takes place in mitochondria.

Mitochondria have their own DNA which is smaller than nuclear DNA and are circular in shape like bacterial DNA. It is called the powerhouse of the cell because ATP synthesis takes place in mitochondria which provide energy to the cell.

The ATP is produced through the process of oxidative phosphorylation which occurs in the matrix and mitochondrial membrane. In oxidative phosphorylation, ATP is produced by energy released from the oxidation of NADH and FADH₂ molecules.

Therefore the correct answer is a,c, and d.

Answer 2

Answer:

Option (a), (c) and (d).

Explanation:

The prokaryotes lacks the nucleus and the membrane bound organelles. Eukaryotes have well defined nucleus and the endomembrane  system is present in eukaryotes.

The main site of the oxidative phosphorylation is the mitochondria in case of eukaryotes. The mitochondria are known as semi autonomous organelle as it contains its genetic material. As the oxidative phosphorylation occurs in mitochondria, this is the main site of ATP production. The mitochondria is a membrane bound organelle and absent in case of prokaryotes.

Thus, the correct answer is option  (a), (c) and (d).
