I: | They are not included in the endomembrane system. |
II: | Rough ER is the major site for synthesis of lipids. |
III: | They are not bound by a membrane |
I. | The major lipids are phospholipids |
II. | Peripheral proteins are only partially buried in the membrane |
III. | Lateral movement of lipids in protein bilayer is measured as its fluidity |
1. | Only I is correct |
2. | Only III is correct |
3. | Only II and III are correct |
4. | Only I and III are correct |
1. | the outermost layer is the cell wall |
2. | all three layers act together as a single protective unit |
3. | the cell membrane staining properties make some bacteria Gram positive |
4. | carbohydrate is the biomolecule absent in all three layers |
1. | Mitochondria - produce cellular energy in the form of ATP |
2. | Golgi body - provides packaging material |
3. | Lysosomes - secrete hydrolytic enzymes |
4. | Endoplasmic reticulum - synthesis of lipids |
1. | a layer present between cell wall and membrane of bacteria |
2. | cell wall of bacteria |
3. | bacterial cell glyco-engineered to possess N-glycosylated proteins |
4. | a layer surrounding the cell wall of bacteria |
1. | All plants are composed of different kinds of cells which form the tissues of the plant. |
2. | Animal cells have a thin outer layer which is today known as ‘plasma membrane’. |
3. | Cells divide and new cells are formed from pre-existing cells. |
4. | The presence of cell wall is a unique character of the plant cells. |
