Term
Cellular Respiration
Definition
The breakdown of food molecules in the presence of oxygen in order to release chemical energy in the form of ATP
Term
Cellular Respiration Equation
Definition
C6H12O6 + 6O2 -------------------> 6CO2 + 6H2O + ~38 ATP
Term
Glycolysis
Definition
The first step of cellular respiration, in which glucose is broken down
Term
Glycolysis Reactants and Products
Definition
Reactants- 1 Glucose Molecule
6 carbon Atoms
Products- 2 Pyruvate Molecules and
NADH and NADPH 3 carbon Atoms
Term
Glycolysis Location
Definition
Cytoplasm of the cell
Term
Kerbs Cycle
Definition
The second step of cellular respiration, occurring within mitochondria and producing energy-carrying molecules. It's also known as the citric acid cycle
Term
Kerbs Cycle Reactants and Product
Definition
Reactants- 2 private molecules
Products- CO2,NADH, NADPH, FADH2, ATP
Term
Kerbs Cycle Location
Definition
Mitochondrial Matrix
Term
Electron Transport Chain
Definition
A group of proteins in the cristae of the mitochondria work to pump H+ ions up the concentration gradient. When they are allowed to move down the concentration gradient they move through ATP Synthase which produces ATP for every incoming H ion.
Term
Electron Transport Chain Reactants and Products
Definition
Reactants- NADH, NADPH, FADH2, H+ Ions
Products- LOTS OF ATP
Term
Electron Transport Chain Location
Definition
Mitochondrial Cristae
Term
Mitochondria
Definition
Membrane-enclosed organelles that are the main site of energy production
Term
Chlorophyll
Definition
The green coloring matter of leaves and plants
Term
Inorganic
Definition
Not formed by or involving organic life or the products of organic life
Term
Glucose
Definition
Sugar which is broken down for ATP in Cell Respiration
Term
Matrix
Definition
The inner space in the membrane
Term
Cristae
Definition
The folds of the inner membrane
Term
Outer Membrane
Definition
The membrane that surrounds the mitochondria
Term
Inner Membrane
Definition
The inside of the membrane
Term
Photosynthesis and Cell Respiration
Definition
They are alike because they both make their food and break it down
Term
Photosynthesis Equation
Definition
C6H12O6+6O2 6H20+6CO2+Energy
