Energy
The ability to do work or cause change.
ATP
an organic molecule used for short-term energy storage and transport in cells.
Hydrolysis
The reaction of an organic chemical with water to form two or more new substances, often involving the cleavage of chemical bonds.
ATP-ADP Cycle
The reversible process of converting ATP to ADP and vice versa, where ATP stores energy and ADP needs to be recharged to be used as a power source.
Energy coupling
The transfer of energy from one chemical reaction to another, where an energetically favorable reaction (exergonic) is linked with an energetically unfavorable reaction (endergonic).
Exergonic reaction
A reaction where energy is released to the surroundings, with the bonds being formed stronger than the bonds being broken.
Endergonic reaction
A reaction where energy is absorbed from the surroundings, with the bonds being formed weaker than the bonds being broken.
Glucose
A simple sugar and an important source of energy in cells.
Polypeptide
A chain of amino acids linked by peptide bonds, forming a protein.
Glycolysis
The metabolic pathway that converts glucose into pyruvate, producing ATP.
Oxidative phosphorylation
The process of generating ATP through the transfer of electrons in the electron transport chain.
ADP
the uncharged form of ATP that needs to be recharged to regain its energy.
Chemical reaction of atp to adp
ATP + H2O → ADP + Pi + energy
Chemical reaction of ADP to ATP
ADP + Pi (inorganic phosphate) + energy → ATP + H20
Light-Independent Reaction
Chemical reactions during photosynthesis that convert carbon dioxide and other compounds into glucose, taking place in the stroma.
Rubisco
A plant enzyme which catalyzes the fixing of atmospheric carbon dioxide during photosynthesis by catalyzing the reaction between carbon dioxide and RuBP.
Ribulose Bisphosphate
An organic substance that is involved in photosynthesis, reacts with carbon dioxide to form 3-PGA.
Fixation
RuBisCO catalyzes a reaction between CO2 and RuBP, which forms a six-carbon compound that is immediately converted into two three-carbon compounds.
Reduction
ATP and NADPH use their stored energy to convert the three-carbon compound, 3-PGA, into another three-carbon compound called G3P
Regeneration
One of the G3P molecules leaves the Calvin cycle to contribute to the formation of the carbohydrate molecule which is commonly glucose
Photosynthesis
The process through which light energy is converted into chemical energy stored in sugar and other molecules.
Heterotrophic nutrition
One of the two major modes by which organisms acquire organic compounds for energy, where they are unable to make their own food and live on compounds produced by other organisms.
Heterotrophs
Organisms that are unable to make their own food and live on compounds produced by other organisms.
Stomata
Tiny openings on the surface of leaves that allow gases, such as carbon dioxide and oxygen, to enter and exit.
Chloroplasts
Organelles found in plant cells that contain chlorophyll and are the site of photosynthesis.
Grana
Stacks of thylakoid sacs found within chloroplasts.
Chlorophyll
The green pigment found in thylakoid membranes that absorbs light during photosynthesis.
Photosystems
Groups of pigments and proteins located in the thylakoid membranes that initiate the light-dependent reactions of photosynthesis.
Light-Dependent Reactions
The first stage of photosynthesis, which involves the absorption of light energy and the conversion of that energy into chemical energy in the form of ATP and NADPH.
Calvin cycle
The second stage of photosynthesis, which involves the conversion of carbon dioxide into sugar using the energy stored in ATP and NADPH.
Electron transport chain
A series of proteins located in the thylakoid membrane that transfer electrons during the light-dependent reactions of photosynthesis.
ATP synthase
A transmembrane protein complex that uses the energy from the movement of hydrogen ions to synthesize ATP.
Chemiosmosis
The process by which hydrogen ions move through ATP synthase, allowing the synthesis of ATP.
NADPH
An energy carrier molecule that is formed during the light-dependent reactions of photosynthesis and is used in the Calvin cycle.
Solar energy
Energy from sunlight that is captured and converted into chemical energy during photosynthesis.
Aerobic Respiration
A set of metabolic reactions that occur in the presence of oxygen in a cell to convert chemical energy into ATPs.
Anaerobic Respiration
A process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.
Electron Acceptor
A molecule that accepts electrons during cellular respiration.
ATP
a molecule that stores and releases energy for cellular processes.
Glycolysis
The first step of cellular respiration, where glucose is broken down into pyruvic acid.
Krebs Cycle
A series of chemical reactions that occur in the mitochondria during aerobic respiration to produce ATP.
Mitochondria
Organelles in eukaryotic cells where aerobic respiration takes place.
Carbon Dioxide
A gas produced as a by-product of aerobic respiration.
Water
A molecule produced as a by-product of aerobic respiration.
Oxidation
The process of losing electrons during cellular respiration.
Location
Aerobic respiration occurs in the mitochondria of eukaryotic cells, while anaerobic respiration occurs in the cytoplasm of both eukaryotic and prokaryotic cells.
End Products
The final products of aerobic respiration are carbon dioxide, water, and energy, while the end products of anaerobic respiration can include acids, alcohols, gases, and energy.
Nature of the Process
Aerobic respiration is comparatively longer and more efficient than anaerobic respiration.
Glucose
The main fuel source for aerobic respiration.
Oxygen
The electron acceptor in aerobic respiration.
Sulfur and Nitrogen
Other electron acceptors that can be used in anaerobic respiration.
Sunlight
The initial source of energy for photosynthesis, which is converted into chemical energy in the form of glucose.
Chloroplasts
Organelles in plant cells where photosynthesis takes place.
Chlorophyll
A green pigment found in plants that is responsible for absorbing light energy for photosynthesis.
Pigments
Colorful compounds that absorb light from the sun.

Accessory pigments
Other pigments in plants that absorb wavelengths of light that chlorophyll cannot effectively absorb.
Chlorophyll a
The core pigment in plants that absorbs sunlight for photosynthesis.
Chlorophyll b
A pigment similar to chlorophyll a but with a slightly different absorption spectrum.
Carotenoids
Pigments that absorb light from violet to greenish-blue range and appear yellow or yellow-orange.
Anthocyanins
Pigments that give color to flowers, leaves, and fruits and can appear red, purple, or blue.
