Term | Definition |
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 |
