Term
Metabolic Pathway
Definition
Enzyme-mediated reaction or pathway, can be exergonic or endergonic
Term
ATP
Definition
The charged up main energy for your body uses, consists of a nucleotide bade, 5-carbon sugar, and three phosphate tail
Term
ADP
Definition
The uncharged batter form that has only 2 phosphates on its tail, a 5-carbon sugar, and a nucleotide base
Term
Endergonic Reaction
Definition
Energy reaction that requires energy input
Term
Exergonic Reaction
Definition
Energy reaction that gives off energy
Term
1st Law of Thermodynamics
Definition
Energy cannot be created nor destroyed
Term
Enzyme
Definition
A type of protein that speeds up a chemical reaction by lowering activation energy
Term
Induced-fit Model
Definition
As a substrate binds to an active sit, it changes the enzyme's shape to make a better fit and promote chemical change
Term
Active Site
Definition
Part of an enzyme where enzyme interacts with its substrate
Term
Substrate
Definition
Reactant for a specific enzyme-mediated reaction
Term
Activation Energy
Definition
The minimum amount of energy required to start a reaction
Term
Products
Definition
The end result of a chemical reaction
Term
2nd Law of Thermodynamics
Definition
In any energy transfer, you wind up with a lower quality energy form
Term
Reactants
Definition
The starting ingredients that go into a chemical reaction
Term
Chemical Equilibrium
Definition
In a reversible reaction, the time at which the reaction is running at the same pace in both directions
Term
Intermediates
Definition
Any substance formed between the start and conclusion of a pathway
Term
Autograph
Definition
Organism that is capable of making its own food
Term
Chloroplast
Definition
Organelle where photosynthesis occurs
Term
Krebbs Cycle
Definition
2nd stage of respiration
Term
Photosynthesis
Definition
Combination of water, Carbon Dioxide and light engery to produce sugar
Term
Aerobic Respiration
Definition
burning fuels without oxygen
Term
Stomtata
Definition
Pores in a leaf that allow gas exchange
Term
Pigment
Definition
Light absorbing chemical
Term
Electron Transport System
Definition
A series of proteins that carry electrons to convert ADP to ATP
Term
Alcoholic Fermintation
Definition
Type of anearobic respiration that creates alcohol as a waste product
Term
Alcoholic Fermintation
Definition
type of fermination that occurs in plants
Term
Glysolysis
Definition
First stage of cellular respiration; the breaking of glucose
Term
Cellular Repsiration
Definition
Cellular breakdown of glucose to release energy
Term
Light dependent reaction
Definition
first stage of photosynthesis; aka photolysis
Term
Calvin Cycle/ Lt. independent reaction
Definition
second stage of photosynthesis; also called the DARK cycle
Term
Stroma
Definition
liquid portion of chloroplasts
Term
ATP/ Adenosine Triphosphate
Definition
chemical in organisms used to store and release energy
Term
Heterotroph
Definition
Organism NOT capable of making its own food
Term
Chlorophyll
Definition
Pigment in plants that collects light engery
Term
NAD
Definition
Coenzyme molecule that accepts electrons in chlorophyll and becomes a charged battery
Term
ATP synthase
Definition
Protein that converts ADP to ATP
Term
Thylakoid
Definition
Stack of membranes where photosynthesis occurs in chlorplasts
Term
lactate Fermintation
Definition
type of fermintation that occurs in animals and produces muscle cramps
Term
NADP
Definition
Coenzyme molecule that accepts electrons in chlorophyll and becomes a charged battery
