Document Summary
Bisc 220: cell organelles, the importance of compartmentalization within the cell the physical separation of cell funcitons, allows different chemical environments to exist within the cell ph: allows enzymes to function efficiently. Ionic gradients: generation of atp in mitochondria i. ii: organelles are involved with five types of process: i. ii. iii. iv. v. Energy storage: lipid and polysaccharide granules (glycogen, starch) Energy metabolism: chloroplast and mitochondrion: mitochondrion is singular, mitochondria is plural. Structural and transport functions: cytoskeleton, plasma membrane: the plasma membrane. It is a continuous that surrounds the fluids and other structures of a cell. The membrane is composed of a lipid bilayer with proteins floating within it and protruding from it. Some proteins transvers the membrane, with one part exposed on the inner cytoplasmic side and the other on the outer face of the cell: the plasma membrane acts as a selectively permeable barrier.
