- How does facilitated diffusion work?
- What is the solution? and why?
- What type of reaction is this? photosynthesis starts with co2 and h2o molecules, using energy absorbed from sunlight, produces energy-rich sugar molecules
- What is the active sight?
- Why is the structure of a phospholipid helpful and clever?
- a The hydrophilic heads face the outside of the membrane while the tails make up the inside, and only the nonpolar, hydrophobic molecules that are soluble in lipids can easily pass through the membrane
- b The sight where the enzyme and substrate react together, specific because the active sight only fits one substrate
- c Enzymes, and Because enzymes act as biological catalysts that increases the rate of a reaction without itself being changed into a different molecule, smushes down energy barrier
- d Endergonic reaction
- e The protein receives the molecule and changes shape to launch it out to other side
5 Multiple choice questions
- A solution whose pH is lower than that of the cells, cell gains water, pops
- A chemical that resembles the enzymes normal substrate, binds to active sight, irreversible
- The diffusion of molecules across the biological membrane, requires no work
- Lipids, mostly phospholipids
- The way cells release energy, chemical process that uses oxygen to convert the chemical energy stored in fuel molecules to form chemical energy that the cell can use to perform work
5 True/False questions
What is an example of an enzyme inhibitor? → A chemical that resembles the enzymes normal substrate, binds to active sight, irreversible
What is energy coupling? → The use of energy released from exergonic reactions to fuel necessary endergonic reactions
What is induced fit? → A specific reactant that an enzyme reacts on, fits into the active sight
Are inhibitors always harmful? → A specific reactant that an enzyme reacts on, fits into the active sight
What is an endergonic reaction? → A reaction that requires energy, its products have more energy than its reactants, energy is absorbed through surroundings as reaction occurs, energy stored in covalent bonds of product molecules
