If an enzyme inhibitor binds at a site other than the active site of the enzyme, the nature of the inhibitor is described as
icang [17]

Answer:

B. non-competitive

Explanation:

As opposed as competitive inhibition, the non-competitive one does not bind with the active region of the enzyme. However, it does reduce the efficiency of the reaction because it changes the protein structure, making it unavailable for substrate.

Reversibility is related to the possibility of the reaction to be undone. If the bond is covalent, the enzyme will not return to its active state, so that would be a non-reversible bind.

Which organelle in the plant cell would mainly help the cell take water or get rid of water?
aliya0001 [1]
Plants regulate their water levels in two main ways: Stoma and Vacuoles.

Stoma are bean shaped cells on the leaf that allow water and gas to exit. They open and close to regulate water.

Vacuoles are organelles that store water and fluids, which help regulate them.

Which best describes oogenesis and spermatogenesis?
pochemuha
The answer is <span>B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.</span>
