Respiration Flashcards
Is a process that breaks down complex carbon compounds into simpler molecules and simultaneously generates ATP.
Respiration
are used to power other metabolic processes
ATPS
respiratory site of the cells (ATP)
Mitochondrion
2 types of Respiration
Aero and Anaero
requires oxygen as the terminal electron acceptor.
Aerobic respiration
respiration without oxygen, often called fermentation
Anaerobic
Importance of respiration
- Production of ATPs
a. Direct Substrate Phosporylation
b. Chemiosmotic Phosphorylation
e. g. Oxidative Phosphorylation - Production of NADH
strictly dependent on Oxygen
Strictly aerobes or obligate aerobes
presence of Oxygen kills the organisms
Obligate anaerobes
may live/respire in the absence or presence of Oxygen
may live/respire in the absence or presence of Oxygen
Three Stages of Aerobic respiration
- Glycolysis
- Kreb’s Cycle
- Electron Transport Chain/System
Embden-Meyerhoff Pathway
constitutes the major portion of ANaerobic respiration and is also the first part of aerobic respiration.
Glycolysis
citric acid cycle – one of the intermediates is ___ , anion of ___
citrate;citric acid
was carried out by Hans Krebs
Kreb’s Cycle
several intermediates are tricarboxylic acids
tricarboxylic acids cycle
The steps that transport protons from the matrix to the crista lumen, establishing a proton/hydroxyl chemiosmotic gradient.
