Enzymes & Biochem Reactions
The breaking and creating of bonds between different substances
What are chemical reactions?
carries/stores energy for cell functions.
What is ATP?
a type of protein that speed up biochemical reactions by lowering the activation energy.
What are enzymes?
Also referred to as autotrophs, these receive energy from nonliving sources.
What are producers?
The amount of energy needed to make a chemical reaction start
What is activation energy?
Adenine, ribose, and 3 phosphate groups create this structure
What is ATP?
When an enzyme is no longer in its normal shape it is referred to as this.
What is a denatured enzyme?
Receiving energy from living or once living sources.
What are consumers?
Substances that are made by a chemical reaction
What are products?
When the third phosphate of the structure is removed, it becomes this.
What is ADP?
This is the model used to represent enzymes binding to substrates.
What is the lock and key model?
Receiving energy from chemicals is called this.
What is chemosynthesis?
Absorbing/storing energy ex: photosynthesis
What is an endothermic reaction?
This is where the highest energy bond is located.
What is between the 2nd and 3rd phosphate?
Enzymes are this since they speed up chemical reactions.
What are catalysts?
The energy level decreasing as each level consumes the other is referred to as this.
What is the Rule of 10?
Substances that are changed during a reaction
What are reactants?
This is where our energy comes from. Ex: Food
What are macromolecules?
This slows down reactions.
What are competitive inhibitors?
Shows multiple food chains at once, and how they interconnect
What is a food web?
