Cell Respiration

Cellular respiration is a series of controlled reactions in which complex molecules are broken down into darobn dioxide and water, and energy is released. Some of the energy is conserved on ATP molecules. In turn, ATP powers most of the working processes of the cell. ... Glycolysis, Krebs Cycle, Electron Transport.

Cytokinesis, the division of the cytoplasm and cell membrane of a cell, usually occurs after the nuclear genetic division in the mitosis or meiosis process.

Photosynthesis

Nearly all life depends on the biochemical process photosynthesis (photo=light, synthesis=putting together), is the production of glucose from the combination of sunlight, carbon dioxide and water, with oxygen as a waste product.

Active and Passive Transport

Poster text:
• Passive Transport - All cells perform passive transport. It is passive because the cell does not expend any energy (in the form of ATP) to move a particular molecule or ion across its membrane. Passive transport is generated by the principle of diffusion. Driven only by the natural energy of atoms as they bounce off each other, diffusion is the tendency of molecules of one type in a solution to move from an area of greater concentration to an area of lesser concentration until equilibrium is reached. When this occurs across the membrane of a cell, it is called transport. If the diffusing molecules are H2O (water), the process is called osmosis. The membrane of a cell is selectively permeable, meaning that only some types of molecules (commonly water) are allowed to move through in either direction. • Active Transport takes place when a cell requires that molecules be moved against the natural flow of diffusion. In this process transport proteins embedded in the cell's membrane by shape to specific types of molecules. Using energy supplied by the cell (in the form of ATP), the transport proteins move molecules through the membrane. Active transport often involves the movement of two different types of molecules in opposite directions, with the end result being the return on the transport portion to its initial shape.
