Study Notes
Blood Flow and Oxygen
- Blood flows through the lungs during each cycle through the body.
- Oxygen is picked up in the alveoli of the lungs.
- The oxygen is used by cells.
Protoplasm Composition
- Protoplasm is the collective name for the substances that make up a cell.
- Protoplasm is mainly composed of water, electrolytes, proteins, lipids, and carbohydrates.
Proteins
- Some proteins act as carriers for substances during facilitated diffusion.
- Some proteins are ion channels that allow for the passage of ions into or out of the cell.
- Some proteins bind to laminins.
- Laminins are large cross-shaped molecules with multiple receptor domains in the extracellular matrix.
Intercellular Connections
- Junctions between cells can either fasten cells to each other or to surrounding tissues.
- Junctions between cells can permit material transfer from one cell to another.
ATP
- Energy is released from nutrients and used to synthesize adenosine triphosphate (ATP).
- Mitochondria synthesize ATP.
- ATP is transported out of the mitochondrion.
- ATP diffuses through the cell to release energy for cellular functions.
