cell processes

TermDefinition
Diffusion Materials move from a high concentration to a lower concentration until equal on both sides. A form of Passive Transport because no energy is needed to do it.
Osmosis Movement of water by diffusion. A form of Passive Transport because no energy is needed to do it.
Active Transport When the cell uses energy to go from a lower concentration to a higher concentration - against equilibrium. (engulf or use transport protein to carry in or out) (ex.bone cell bringing in calcium)
Aerobic Respiration When you eat and breath in oxygen to make ATP energy for your cells.
Anaerobic respiration (Fermentation) A form of cellular respiration that occurs when oxygen is absent or scarce. Lactic Acid builds up and causes pain. (Runner in marathon)
Metabolism All the chemical activities in the cell that make new molecules and bread down molecules for the cell to use. (lysosome, ribosome, mitochondria are examples you know)
organelles that do metabolism lysosome- break down and recycle ribosome- make protein mitochondria- break glucose and oxygen apart to get ATP energy
How do Amoeba get food into their cell Engulf it by surrounding it with its cell membrane- Psudopods. This is Active Transport because the Amoeba must use energy to do this.
examples of diffusion when you smell cookies baking in the kitchen from the front door, color of the tea from a tea bag in hot water,
examples of osmosis water coming into a cell, soak in a bath until water enters your skin and you wrinkle.
Transport Protein A protein that will carry a molecule in or out of a cell. This is Active Transport because it requires the cell to use energy to do this.
solute the substance that is dissolved in water.
passive transport movement of material across a membrane or in a space without using energy
solution the solvent and solute mixture
solvent the liquid you dissolve the solute with
equilibrium when the concentration is equal on both sides of a membrane or in a space
selectively permeable membrane membrane that allows some things through and not others
