Cellular Respiration Notes

aerobic

aerobic

type of cellular respiration that requires oxygen

Anaerobic

type of cellular respiration that does not require oxygen

ATP Synthase

an enzyme that plays a crucial role in cellular energy production. It is like a tiny molecular machine found in the mitochondria of cells.

Autotroph

organism that makes its own food

Calorie

a unit of energy

Cellular Respiration

process in which cells break down glucose and make ATO for energy

chemical

any substance that has a definite composition. It is made up of specific elements or compounds in a fixed ratio

consumers

organism that consumes other organisms for food

Electron transport chain

series of electron transport molecules that pass high energy electrons from molecule to molecule and capture their energy

fermentation

Type of anaerobic respiration that includes glycolysis, followed by the conversion of pyruvic acid to one or more other compounds in the formation of NAD+

Glycolysis

first stage of cellular respiration in which glucose is split in the absence of oxygen to form two molecules of pyruvate(pyruvic acid) into (net) molecules of ATP

Heterotroph

organism that gets food by consuming other organisms

Kinetic (energy)

the energy an object has because of its motion. The faster an object moves the more kinetic energy it has.

Krebs Cycle

second stage of aerobic respiration in which two pyruvate (pyruvic acid) molecules from the first stage react to form ATP, NADH and FADH2

Metabolism

Sum of all the biochemical reactions in an organism

Photosynthesis

process of using the energy in sunlight to make food (glucose)

Action Potential

a rapid sequence of changes in the voltage across a membrane

Producers

Organisms that produces food for itself and other organisms

Thermal

Is released as a by product of the process

ATP

the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate
