Aerobic Respiration Flashcards
Aerobic respiration
a process by which organisms break down glucose, releasing energy for the synthesis of ATP
Aerobic cellular respiration
requires oxygen. net reaction : C6 H(12) (O6)+6O(2)–>6CO(2) 6H(2)O +30-32ATP
ATP
the source of energy for use and storage at the cellular level
3 stages of Aerobic cellular respiration
Glycolysis, Krebs Cycle, Electron Transport Chain (ETC)
Glycolysis
occurs in the cytoplasm of the cell. Glucose is split into two pyruvate molecules in a series of actions. 2ATP, electrons collected for transport to the ETC
Krebs Cycle
pyruvate from glycolysis diffuses into the matrix of the mitochondria. A series of 8 reactions then occurs. 2ATP, byproduct Carbon Dioxide is released.
collect electrons to transfer to the ETC which will generate more ATP
Electron Transport Chain
proteins on the membranes of the mitochondrial cristae. Electrons of glycolysis and krebs cycle flow between the membrane protein supplying energy for 26-28 ATP to be made.
Build up of electrons at the end of the chain is removed by oxygen, combines with hydrogen to make water.
maximum molecules generated during aerobic respiration
30-32ATP
ATP
main energy storage molecule. The energy stored in the bond linking the final 2 phosphates is released when this bond is broken and is then used by cells.
Importance of the process of aerobic respiration in cells.
AS provides energy to the living organisms to perform all the essential functions of life.
What is in a mitochondrion
Crista, matrix, outer membrane, inner membrane, intermembrane space
Where is crista located
folds of the inner membrane
Where is matrix
Inside the inner membrane
Where is outer membrane
the shell outside
where is inner membrane
the layer below outer shell
