Which of the following enzymes is absent in
mitochondria?
(a) Aconitase
(b) Malic dehydrogenase
(c) Fumarase
(d) Hexokinase
Answers
Hexokinase
Explanation:
(d) Hexokinase enzymes is absent in mitochondria.
- Hexokinase is the underlying chemical of glycolysis, catalyzing the phosphorylation of glucose by ATP to glucose-6-P.
- It is one of the rate-constraining catalysts of glycolysis.
- Its action decreases quickly as ordinary red cells age. Patients with hemolytic ailment.
- It is essential to endure at the top of the priority list that hexokinase action ought to be raised in patients with hemolytic ailment, and that obviously ordinary hexokinase action within the sight of hemolytic frailty may, truth be told, speak to hexokinase insufficiency.
"(d) Hexokinase"
Explanation:
The external layer additionally contains catalysts associated with such different exercises as the stretching of unsaturated fats, oxidation of epinephrine, and the corruption of tryptophan. These catalysts incorporate monoamine oxidase, rotenone-coldhearted NADH-cytochrome c-reductase, kynurenine hydroxylase and unsaturated fat Co-A ligase. Interruption of the external layer grants proteins in the intermembrane space to spill into the cytosol, prompting cell death.
The mitochondrial external film can connect with the endoplasmic reticulum (ER) layer, in a design called MAM (mitochondria-related ER-film). This is significant in the ER-mitochondria calcium flagging and is engaged with the exchange of lipids between the ER and mitochondria. Outside the external film there are little (distance across: 60å) particles named sub-units of Parson.
