Chemical Reactions and Enzymes Flashcards
Reactants
Elements/compounds that engage in chemical reactions
Products
Elements/compounds that are produced in a chemical reaction
Metabolism
All chemical reactions that occur inside an organism
What is the function of a catalyst?
To speed up a chemical reaction
How does a catalyst function?
By reducing the reactions activation energy
What is activation energy?
The amount of energy needed for a chemical reaction to occur
What is a chemical reaction?
The process by which one set of chemicals changes into another set of chemicals
Endothermic Reaction
Absorbs energy from surroundings
Exothermic Reaction
Releases energy into surroundings
A chemical reaction must be ___ or ___.
Endothermic or exothermic
What type of organic compound is an enzyme?
Protein
Enzymes, which speed up the rate of reactions, are biological ___.
Catalysts
How specific are catalysts?
Very, extremely, super-duper important
Substrate
Reactants in enzymes
Active site
Where substrate enter
Product
What the enzyme releases
What is the lock and key model?
The active site/substrate’s complementary shape
Denature
- Happens if pH/temperature is wrong
- Bonds break
- Shape changes
- Can no longer function
Are enzymes reusable?
Yes!!!!!!!
Three factors that affect the functioning of an enzyme
- Temperature
- pH
- Regulatory molecules
