The electron transport chain is named for Select one: a. the removal of unnecessary electrons from the cell b. the conversion of
Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.

Elza [17]

c. The radius articulates to the wrist closest to the thumb

Explanation:

Ulna and radius are the two bones of the forearm. These bones articulates with the humerus and carpels of the hand.

b. The radius forms the point of the elbow: The elbow joint is the hinge joint that forms between the proximal ends of the radius and ulna in the forearm and distal ends of the humerus. The radius forms a pointed end.

c. The radius articulates to the wrist closest to the thumb: The wrist forms a complex joint. It forms a transition between the hand and the forearm. The radial deviation in the wrist forms the basis for the movement of the tilting of the wrist joint towards the thumb.
