Biogeochemical Cycles

The movement of abiotic factors between the living and nonliving components within ecosystems; also known as nutrient cycles

Abiotic Factor

Any nonliving component of an ecosystem

Biotic Factor

Any living component of an ecosystem

Ecosystem

A system composed of organisms and nonliving componenets of an envrinment

Carbon Cycle

The movement of carbon through the ecosystem, from the air into producers and back into concsumers

Producer

An organism that uses a primary energy source to conduct photosynthesis or chemosynthesis

Adenosine Triphosphate (ATP)

A molecule that provides energy for cellular reactions and processes

Adenosine Diphosphate (ADP)

A molecule that has provided energy for cellular reactions, can bind to a phosphate group again to store more energy

Photon

A particle of light

NADP

An energy storage molecule found in plant cells, it can bind to a proton (H+) to store energy

NADPH

An energy storage molecule found in plant cells, already storing energy through the bond between NADP+ and H+

NAD+

An energy storage molecule found in all cells, it can bind to a proton (H+) to store energy

NADH

An energy storage molecule found nin all cells, storing energy in the bond between NAD+ and H+

FAD

An energy storage molecule found in eukaryotic cells, it can bind to protons (H+) to store energy

FADH2

An energy storage molecule found in eukaryotic cells, storing energy in the bonds between FAD and (H+)

Photosynthesis

A process in which solar radiation is chemically captured by chlorophyll molecules and through a set of controlled chemical reactions resulting in the potential chemical energy in the bonds of carbohydrate molecules.

Where does photosynthesis take place?

In the Chloroplasts of a plant cell

Grana

Stacked columns of Thylakoids

Thylakoid membrane

A membrane-bound compartment inside the choloroplast, it is the site of all light-dependent reactions

Chlorophyll

Found within the thylakoid, it collects the light energy and has the green pigment of the plant

Aerobic Respiration

The use of oxygen to break down sugars into CO2 and energy

Anaerobic Respiration

The breakdown of sugars into CO2 and energy without the aid of oxygen

Anerobic Respiration is also called this:

Fermentation

Which provides less energy, Aeorbic or Anerobic Respiration?

Anaerobic

True or Fals: Glycolysis occurs in all cells

True
