The description of a cell energy process is listed below.
Bumek [7]

Answer:

The electron transport chain

Explanation:

During the citric cycle in the matrix of the mitochondria, the NAD+ and FAD+ the metabolic cycle are reduced to NADH and FADH₂ through accepting electrons. The energy harnessed from the metabolic cycle is used to develop a proton motive force across the mitochondrion intermembrane. This potential energy is harnesses by ATP synthase to create ATPs. As the H+ ions drain back into the matrix of the mitochondria, they are used to reduce oxygen to water. In this redox reaction, the FADH₂ and NADH donate their electrons  and are recycled back to the citric cycle in their oxidized form.

Which statement is true for all sexually reproducing plants and animals? a) The process of mitosis always produces diploid cells
vazorg [7]

Answer:

d) The process of meiosis produces haploid cells

Explanation:

<em>Meiosis is a form of cell division that involves sex cells. A single diploid sex cell divides twice (meiosis I and meiosis II) to produce four haploid daughter cells. Meiosis is sometimes referred to as reductional cell division because involves halving of the chromosome number of the parent cell.</em>

When meiosis takes place in animals, the haploid cells produced can be directly referred to as gametes. However, in plants, haploid cells give rise to haploid gametophytic generations or simply gametophytes. The gametophytes eventually gives rise to gametes.

Hence, the most correct option is d.
