Cards

Term
Energy
Definition
The ability to do work
Term
Reactant
Definition
A substance that reacts (is used) in a chemical reaction. Left Side
Term
Product
Definition
A substance that is produced in a chemical reaction.Right Side
Term
Chemical Reaction
Definition
A process that results in substances forming or breaking into new substances.
Term
Autotroph
Definition
Producer
Term
Heterotroph
Definition
Consumers
Term
Chloroplast
Definition
Double-membrane organelles in plants and some other unicellular eukaryotic cells that are the main site of photosynthesis.
Term
Photosynthesis
Definition
The process of converting light energy to chemical energy; in the process, carbon dioxide and water are converted into oxygen and sugars
Term
Thylakoid Membrane
Definition
A membranous sac within chloroplasts on which the light reactions of photosynthesis occur
Term
Grana
Definition
The stacks of thylakoid membranes within chloroplasts
Term
Stroma
Definition
The space between the grana in a chloroplast.
Term
Photon
Definition
Each particle of light that shines from the sun
Term
Chemical Bonds
Definition
an attraction between atoms or molecules that allows the formation of chemical compounds, which contain two or more atoms.
Term
ATP
Definition
Adenosine Triphosphate (Very High Energy)
Term
NADPH
Definition
High Energy
Term
How does life on earth depend on photosynthesis?
Definition
Not all life depends on photosynthesis. Some animals use a different process to turn chemicals into chemical energy.If photosynthesis couldn't happen, animals that need oxygen would die.
Term
Light Reactions--steps and the reactants and products
Definition
The light reactions in photosynthesis are dependent on light being there.
LOCATION - Thylakoid
1. Water enters the cell.
2. Sunlight energizes the energy-carrying molecules.( ADP and NADP+ )
3. Oxygen leaves the chloroplast, and ATP and NADPH move on to the Calvin cycle.
Term
Calvin Cycle--steps and the reactants and products
Definition
This reaction does not require light in order to work. It can occur in the light or in the darkness.
LOCATION-Stroma
1. Carbon Dioxide enters the chloroplast.
2. ATP and NADPH arrive from the light reactions.
3. The Calvin cycle uses carbon dioxide, ATP, and NADPH molecules to make glucose.
4. ADP and NADP+ return to the light reactions.
Term
Cellular Respiration Definition
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 + Energy
Term
Glycolysis Definition
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 (Energy Carriers)
3 Carbon Atoms
Term
Glycolysis Location
Definition
Cytoplasm of the cell
Term
Krebs Cycle Definitions
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
Krebs Cycle Reactants and Products
Definition
Reactants-
2 pyruvate molecules
Products- CO2,NADH, NADPH, FADH2, ATP
Term
Krebs Cycle Location
Definition
Mitochondrial Matrix
Term
Electron Transport Chain Definition
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 (Used by H+ Pumps too)
Products-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
A green substance in the thylakoid membranes of chloroplasts that gathers light for photosynthesis.
Term
Inorganic
Definition
considered to be of a mineral, not biological origin.
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
Inner Membrane
Definition
The space between the inner and outer membrane.
Term
Outer Membrane
Definition
The membrane that surrounds the mitochondria
Term
Photosynthesis Equation
Definition
6CO2 + 6H2O + Energy --> C6H12O6 + 6O2
Term
A card that compares Photosynthesis with Cell Respiration
Definition
Cell respiration is the reverse of photosynthesis
