The organelles that are included in the endomembrane system are
1 Golgi complex, Endoplasmic reticulum, Mitochondria and Lysosomes
2 Endoplasmic reticulum, Mitochondria, Ribosomes and Lysosomes
3 Endoplasmic reticulum, Golgi complex, Lysosomes and Vacuoles
4 Golgi complex, Mitochondria, Ribosomes and Lysosomes
Explanation:
Exp:C The system of membranous components whose functions are coordinated is called Endomembrane system. It consist of endoplasmic reticulum, Golgi complex, Vacuoles and lysosomes. - Mitochondria is semi-autonomous cell organelle. - Ribosome is non-membranous cell organelle. \section*{ENDOMEMBRANE SYSTEM}

Which of the following events does not occur in rough endoplasmic reticulum?
1 Protein folding
2 Protein glycosylation
3 Phospholipids synthesis
4 Cleavage of signal peptide
Explanation:
Exp:C Phospholipids synthesis does not take place in rough endoplasmic reticulum. The phospholipids synthesis occur in smooth endoplasmic reticulum. It can synthesis the lipid like cholesterol and phospholipids. It also synthesis and secrete steroid hormones from cholesterol. SER (Smooth endoplasmic reticulum) perform detoxification in liver. RER involved in the synthesis of protein. Function of RER - folding, modification and processing of newly synthesized proteins.

Explanation:
Exp:D A dope test in a test to determine whether an athlete is taking drugs to enhance one's performance. A breathalyzer is a device for estimating blood alcohol content by analyzing the breath of a person is drink, in the initial stages the nervous system is stimulated, and the person becomes hyperactive and talks more.

\(\quad\) Vacuole in a plant cell:
1 lacks membrane and contains air
2 Lacks membrane and contains water and excretory substances
3 is membrane-bound and contains storage proteins and lipids
4 is membrane-bound and contains water and excretory substances
Explanation:
Exp:D Vacuoles are membrane bound organelles present in cells. The membrane of the Vacuoles is composed of phospholipids molecules and trans membrane proteins called Tonoplast. Functions of vacuoles - - Maintains the turgidity of the cell. - Helps to isolate substances that are harmful. - Contains water that helps to keep the plant cell rigid. - Maintains the acidity of the cell cytoplasm and creates an effective environment for proteins to act. - Take part in storage vacuole contain water, minerals, enzyme and excretory waste.
