- Are inhibitors always harmful?
- How is competitive inhibation prevented?
- What is a competitive inhibitor?
- What is selective permeability?
- What is a receptor protein?
- a A protein that's part of the fluid mosaic that fit's the shape of a message just like an enzyme fit's the shape of a substrate
- b No, enzyme inhibition often used for regulation cell metabolism
- c PM allows some substances to cross more easily than others
- d A chemical that resembles the enzymes normal substrate, binds to active sight, irreversible
- e Increasing the number of substrate molecules so theres less of a chance that the inhibitor will get to the active sight first
5 Multiple choice questions
- Exergonic reaction
- The way of an plant/animal to prevent excessive uptake or excessive loss of water
- fluid mosaic of phospholipids and proteins
- The protein receives the solute, ATP phosphorylates the protein, the protein changes shape which causes the solute to be launched on the other side of the membrane where it is more concentrated
- The amount a substance can diffuse down to until it reaches equilibrium
5 True/False questions
How does facilitated diffusion work? → The protein receives the molecule and changes shape to launch it out to other side
What is the energy of activation? → The amount of energy the reactants must absorb to become active and start a chemical reaction/get over the energy barrier
What is an isotonic solution? → A solution whose pH is equal to that of the cell, the cell gains water as quickly as it loses it, stays the same
How are enzymes like assembly lines? → fluid mosaic of phospholipids and proteins
Why are plants healthier in hypotonic environments? → A solution whose pH is lower than that of the cells, cell gains water, pops
