Answer:
D. oxygen is the final electron acceptor.
Explanation:
Oxygen serves as the final electron acceptor in aerobic cellular respiration. The whole pathway includes glycolysis, Kreb's cycle, and oxidative phosphorylation.
Oxidation of NADH and FADH2 formed during glycolysis and Kreb's cycle through electron transport chain during oxidative phosphorylation includes molecular oxygen as the terminal electron acceptor.
The proton motive force generated during the electron transfer from NADH and FADH2 to oxygen gas drives phosphorylation of a large number of ADPs into ATPs.

Through the process of selective breeding. breeders take cats with certain traits and breed them so their offspring will have the desired traits
<u>Answer:</u>
Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism
The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.
excretory system: removes waste from blood.
respiratory system: obtains oxygen so the energy in the nutrients can be extracted.
circulatory system: transports nutrients from small intestine to the othet tissues.
nervous system: regulates and controls digestive functioning.
