Everything Flashcards
(22 cards)
Anabolic reaction
Synthesis of larger molecules from smaller ones
Catabolic reaction
Any chemical reaction/large molecules that breaks into smaller molecules
Substrate
The reactant on which an enzyme works
Active site
A region on an enzyme that binds to the protein or other substance during a reaction
Catalyst
Substance that speeds up the rate of a chemical reaction
Enzymes
Proteins that act is a biological catalyst
Denatured
Loss of an enzymes normal shape so that it no longer functions; caused by A less then optimal pH and temperature
Protein
Chains of amino acids
3 main enzymes
Helicase
DNA polymerase
DNA ligase
Two phases of the cell cycle
Interphase and mitosis phase
What is DNA replication
When DNA makes a copy of it self
What is the complimentary base pairing rule
Hydrogen bonding between Adenine and Thymine mean. Cytosine and Guanine
What does DNA stand for
Deoxyribose nucleic acid
Facilitated diffusion
Movement a specific molecules across the cell membrane’s through the cell membrane of low concentration
Active transport
Energy requiring processes that move materials across a cell membrane against the concentration difference of a low concentration to a high concentration gradient
Osmosis
Diffusion of water across a selectively permeable membrane
Diffusion
Movement of molecules from an area of high concentration to an area of low concentration
Purpose of mitosis
Growth and repair
Anaerobic equation
Glucose –> Energy + lactic acid
Glucose –> ethanol+ carbon dioxide + energy
Photosynthesis equation
Light energy + carbon dioxide + water –> glucose + oxygen
Purpose of enzymes
Speed up reactions
Aerobic equation
Glucose + oxygen –> water + carbon dioxide + energy
