In the last stage of cellular respiration, oxidative phosphorylation, all of the reduced electron carriers produced in the previ
Mumz [18]

Explanation:

ADP, O2, NADH

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycolysis).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration. The process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria this forms a gradient where there is a differential in the number of protons on either side of the membrane the protons  re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP.  At the end of the ET see molecules of oxygen accept electrons and protons form molecules of water.

What two organ systems are most involved in controlling the negative feedback systems of the body?
ololo11 [35]

Answer:

The respiratory system as well as circulatory system (hormonal system) are involved in controlling the negative feedback of our body.

Explanation:

The respiratory system helps in controlling the negative feedback in such a  way that if CO2 level increases in body the system acts in such a way so as to decrease  its level in body . the system attains a normal level by  increasing the blood circulation and increasing the breathing level forcing CO2 outside of our body.

in case of circulatory system, the blood has several hormones released from glands . the most common example is Insulin and Glucagon .

if a person is hypoglycemic then glucagon concentration increases and blood glucose concentration returns to normal and if a person has hyperglycemia then insulin level increases which in turn increases glucose uptake from body and body returns to normal level.

What feature of the skeleton eventually allow a child to maintain balance while walking and running?
Triss [41]
The vertebral column, when seen from the side, has 4 curves: 2 convex curves (cervical and lumbar curves) and 2 concave (thoracic and sacral curves). This curves are the feature of the skeleton that allow a child to maintain balance in the upright position eventually.
When we are born we have a single concave curve throughout the whole vertebral column but, as we grow, still in the early months as we try to hold our head, the cervical curve starts to develop, and later, as we try to sit up, stand up, and walk, the lumbar curve aslo starts to develop. In few years we have all curves fully developed.
