Answer 1

Answer 22.

Mitochondria :-
• This cell organelle is site for cellular respiration, a big amount of ATP (energy) is generated here. Citric acid cycle and electron transport chain of aerobic respiration is performed in mitochondria which generates energy.
• Mitochondria is also known as powerhouse of cell.

Now in question,
Option (c) is correct answer.
Making ATP to power cellular reactions.

Other options -
(a) Peroxisome contains enzymes for fatty acid and amino acid breakdown.
(b) Ribosomes helps in protein synthesis initiation.

For Question 23 and 25.

Endomembrane system :-
• It is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.
It includes -
Nucleus envelope
Endoplasmic reticulum
Golgi apparatus
Ribosomes (at rough endoplasmic reticulum)
Vasicles.

Endoplasmic reticulum -
(a) Rough ER :- Synthesis of new proteins.
(b) Smooth ER :- Synthesis of carbohydrates, lipids, and steroid hormones.

Golgi apparatus -
Sorting, packaging, and distribution of lipids and proteins takes place in the Golgi apparatus.
The cis face is called receiving side of the Golgi apparatus.

Lysosomes -
Lysosomes digest macromolecules, recycle organelles and destroy pathogens.

Answer 23.
Option (c) Golgi apparatus is correct answer.
Golgi apparatus is cell organ for distribution of lipids and proteins.
Endoplasmic reticulum involved in synthesis of protein and lipids.

Answer 25.
Option (c) Endomembrane system is correct answer.
*explained above.

Answer 24.
• There are two membranes present in mitochondria. The outer membrane covers the and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae.
• This cristae contain proteins which are involved in electron transport chain of respiration.
• The portion inside the inner membrane is called matrix of mitochondria.

Now in question,
Option (c) Cristae and mitochondrial matrix is correct answer.
