Unit 1 Review Flashcards
What is active transport?
When molecules move against their concentration gradient to transport across the cell membrane. No energy required
What is the photosynthesis equation?
6O2 + Sunlight +H2O = C6 H12 O6 +6O2
What is a substrate?
It is what binds to the active site. It can also be known as the “lock”
What is an enzyme?
A biological catalyst that increases the rate of a chemical reaction by reducing the amount of energy required to start one
What is a monomer?
The building block of a macromolecule
What does hypertonic mean?
The cell will shrivel up and die because the solute concentration inside is less than the solute concentration outside.
What does hypotonic mean?
The cell will swell up, explode, and die because the solute concentration inside is greater than the solute concentration outside
What does precursor mean?
Precursor is positive feedback that starts a process. The output enhances the original stimulus
What is diffusion?
The natural movement of molecules/ions from an area of high concentration to a low concentration. (Smell of bacon)
What is the final result of the light-dependent reactions in photosynthesis?
ATP, O2 & NADPH
What does the photosynthesis equation begin with?
CO2 & H2O
What is an anabolic reaction?
this is when simple molecules are combined to form more complex compounds through dehydration synthesis
What are macromolecules?
Large complex organic molecules. These include Carbohydrates, Lipids, Proteins & Nucleic Acids
Where does cellular respiration occur?
The mitochondria
What does allosteric mean?
Allosteric is negative feedback that stops a process
