KREB'S CYCLE & ELECTRON TRANSPORT CHAIN Flashcards
(21 cards)
It is the sum total of all the biochemical reactions that take place in a living organism.
Metabolism
It is a series of consecutive biochemical reactions used to convert a starting material
into an end product, which is either linear or cyclic.
metabolic pathway
Is all metabolic reactions in which small biochemical molecules are joined together to form larger ones
ANABOLISM
Is all metabolic reactions in which large biochemical molecules are broken down to smaller ones
CATABOLISM
Series of reactions in which the end product of one reaction is the starting of another reaction
LINEAR METABOLIC PATHWAYS
Series of reactions in which the end product of one reaction is recycled as a starting material for another reaction in the same pathway. The end product and the starting material being the same compound
CYCLIC METABOLIC PATHWAY
Is a cell in which the DNA is found in a membrane-enclosed nucleus.
Eukaryotic cell
DNA replication and RNA synthesis
Nucleus
Cellular boundary
Plasma membrane
the water-based material that lies between the nucleus and the outer membrane of the cell
Cytoplasm
generates of most of the energy for a cell
Mitochondria
Contains hydrolytic enzymes needed
for cellular rebuilding, repair, and degradation
Lysosome
site for protein synthesis
Ribosome
Powerhouse of the cell
MITOCHONDRIA
▪ 50% lipid and 50% protein
▪ freely permeable to small molecules.
Outer membrane:
▪ about 20% lipid and 80% protein
▪ Highly impermeable to most substances
Inner membrane
Region between inner & outer membrane
intermembrane space
the net energy produced used for cellular reactions
Adenosine Triphosphate
IMPORTANT NUCLEOTIDE CONTAINING COMPOUNDS in METABOLIC PATHWAYS
- Adenosine Triphosphate
- Coenzyme A
- Flavin Adenine Dinucleotide
- Nicotinamide Adenine Dinucleutide
Active portion is –SH (sulfhydryl group) or as CoA-SH
Derivative of Vit. B5
Coenzyme A
