Q

ATP and ADP

A

ATP: Universal energy molecule

ADP is a empty energy carrier. when another phosphate is added it becomes ATP and carries the unusable energy in the last high energy phosphate bond.

When ATP gives up its energy, it loses a phosphate and becomes ADP and gos back to the cytoplasm and mitochondria to be recharged with energy via respiration.

Q

why is ATP important

A

all cells need energy for cell processes.

these processes use energy in the form of ATP adenosine triphosphate.

ATP is an immediate source of energy to a cell.
can diffuse anywhere and releases energy quickly

each cell produces its own ATP from foods

Q

Aerobic respiration

A

aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose.

occurs in the cytoplasm and mitochondria

uses oxygen

glucose + oxygen => carbon dioxide + water + energy

releases a large amount of ATP

Q

glycolysis

A

produces 2 ATP when glucose is split into 3 carbon pyruvate molecules releasing H2 and CO2.

including acetyl coenzyme A formation which is a 2 carbon molecule in the cytoplasm

Q

Krebs cycle

A

Produces 2 ATP as a series of reactions breaks up these molecules into H2

occurs in the matrix of the mitcochondria

Q

anerobic respiration

A

gives small yield of ATP from glucose

if there is no oxygen then only glycolysis occurs which is no efficient as only 2 ATP are produced as only glucose can be used
