Jawaharlal Nehru was not unconscious of his indebtedness to Indian history and tradition as a determining factor in the formulation of his policy of non-alignment. What I have done is to give voice to that policy (non-alignment)âI have not originated it.
Lysosomes are found only in animal cells and are vesicles of digestive enzymes. It is a membrane-bounded sac that holds enzymes. It is the little stomach of the cell because it is the center of digestion. Its main function is to clean up the cell by digesting macromolecules and cleaning up broken down organelles.
The transmembrane proteins that cross the bilayer are very important in the active transport of ions and small molecules. Different Membranes of the Cell As you learn more about cell organelles, you will find that they all have a membrane. Organelle membranes do not have the same chemical makeup as the cell membrane. They have different lipids and proteins that make them unique. The membrane that surrounds a lysosome is different from the membrane around the endoplasmic reticulum. Some organelles have two membranes.
