Answer:
The answer is a heme cofactor.
Explanation:
Peroxidase is an enzyme that catalyzes oxidation/reduction reaction by using hydrogen peroxide as a substrate.
Donor+H2O2 ↔ Oxidized donor + H2O
Peroxidase active site can contain a heme cofactor that has an iron ion and a porphyrin molecule that acts as an electron donor to the hydrogen peroxide which is then reduced to water.
Abiotic means is not or never was living.
b. the wind is not a living thing
Answer: A. protein like tubules
B. Microtubules
C. Microfilaments
Explanation:
Cytokinesis in the bacteria is facilitated by the presence of these conserved tubulin-like proteins. Due to the fact that their walls are flexible, constriction of these walls is possible aiding in cytokinesis. Unlike in plant that have rigid cell wall, a cell plate is involved in the formation of a new cell wall between the daughter cells. Network of microtubules determines the position of the cell plate which is mostly like a disc in the middle of the two daughter cells. Cleavage furrow occurs in animal cells which is caused by the action of the contractile ring: a ring of actin microfilament.
The blood-brain barrier is effective against the brain itself mostly because it, like a cell membrane, Controls what nutrients and other things that go into and out of the brain.
