CELL ORGANELLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When this organelle fails, a set of smaller, grain-shaped organelles has difficulty producing proteins. Which organelle is being described?
A
Cell Wall
B
Mitochondria
C
Endoplasmic Reticulum
D
Nucleus
Explanation: 

Detailed explanation-1: -The rough endoplasmic reticulum has many ribosomes on its outer surface and makes proteins the cell needs. The smooth endoplasmic reticulum makes other substances that the cell needs, such as lipids (fats) and carbohydrates (sugars). The endoplasmic reticulum is a cell organelle.

Detailed explanation-2: -The endoplasmic reticulum (ER) is an organelle whose primary function is protein synthesis and folding [1].

Detailed explanation-3: -Ribosomes are small grain-shaped organelles that produce proteins. Proteins are important substances in cells.

Detailed explanation-4: -The smooth ER has the main role in lipid and steroid synthesis, it stored intracellular calcium as well. Without ER in the skeletal muscle fibres, smooth muscle contraction wouldn’t happen. So, cells will die due to the absence of these essential cellular mechanisms.
