Oxygen is the final electron acceptor in the electron transport chain in aerobic respiration The electron transport chain of the mitochondria is the means by which electrons are removed from reduced carrier NADH and transferred to oxygen to yield water. In the cytochrome oxidase complex of the electron transport chain, four electrons interact with a molecule of oxygen and eight hydrogen ions. The four electrons, four of the hydrogen ions and the molecule oxygen are used to form water molecules. In anaerobic respiration the final electron acceptor can be of many types such as Ferric iron which is used by denitrifying bacteria

Saccharomyces cerevisiae is a diploid yeast species that can reproduce either sexually or asexually. An experiment was performed
Savatey [412]

Answer:

D. The first division will reduce the number of chromosomes by half for each daughter cell, and the second division will move single chromatids to each daughter cell.

Explanation:

Gametes are formed by meiosis in diploid gamete mother cells. During gamete formation, the gamete mother cell in the yeast would undergo meiosis I. During first division (meiosis-I), the process of crossing over during prophase-I creates genetic variations and movement of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in each daughter cell.

Two daughter cells are formed by the end of meiosis-I each of which enters meiosis-II. Splitting of centromere and separation of sister chromatids during anaphase-II of meiosis-II results in the movement of single chromatids to the opposite poles of the cells.
