Answer:
The correct answer is option - B. proteins.
Explanation:
The muscle contraction needs two protein that is essential in contraction. The muscle has motor protein myosin and spherical protein actin that are slide on one other in contraction that helps in muscle to contraction.
In the contraction, these protein filaments help to change in length and shape of the muscles. Thin filaments involve actin and thick filament in is myosin filaments.
Thus, the correct answer is option - b. proteins.
The Endoplasmic reticulum is the organelles that is involved in the synthesis of oils.
<u>Explanation:</u>
The endoplasmic reticulum is of 2 types that is the ''smooth endoplasmic reticulum'' and the ''rough endoplasmic reticulum''. The rough endoplasmic reticulum is lined with ribosomes whereas the smooth endoplasmic reticulum is plain.
Since ribosomes are present the rough endoplasmic reticulum is involved in protein synthesis whereas the smooth endoplasmic reticulum is involved in the production of oils or lipids that are required for the cell.
