1) Name the two parts of the common catabolic pathways?
i) Citric acid cycle
ii) Oxidative phosphorylation
2) The process of anabolism is
Anabolism is the synthesis of a large variety of complex molecules from simple precursors. The anabolic reactions are dependent on the supply of energy (as ATP or GTP) and reducing equivalents as (NADPH + H+).
3) In what organelle does the common catabolic pathway take place?
Mitochondrial membrane
4) What is the primary function of NAD+ in the common metabolic pathway?
In metabolic pathways, NAD+ plays a very important role in redox reactions. Oxidation-reduction reactions occur when there is a transfer of electrons from a suitable electron donor to a suitable electron acceptor. Oxidized and reduced forms of NAD+ operating in oxidation and reduction reactions are the prime function of NAD.
5) What two compounds get oxidized (lose hydrogen) in the common metabolic pathway?
Nicotinamide adenine dinucleotide (NAD+)
Flavin adenine dinucleotide (FAD)
6) In what part of the common metabolic pathway is CO2 produced?
Mitochondria (Citric acid cycle)
7) What molecule is used by living systems as a "currency" for storing and transporting chemical energy?
Adenosine triphosphate (ATP) is the energy currency of the living cell.
8) During glycolysis what two 3 carbon fragments are produced?
During glycolysis, two molecules of pyruvate are produced.
9) Under aerobic conditions (oxygen) what molecule does pyruvate react with before it enters the common catabolic pathway?
In the presence of oxygen, pyruvate is converted to acetyl CoA by oxidative decarboxylation. This is an irreversible reaction catalyzed by a multi-enzyme complex known as pyruvate dehydrogenase complex (PDH) which is found only in the mitochondria.
