The <u>brachial artery</u> is located in each upper limb, therefore it supplies the upper limb and the lower limb's main arterial vessel is called the <u>femoral artery</u>.

<h3>What is brachial artery?</h3>

It is the main blood vessel that is responsible for transporting oxygenated blood to supplies the upper limb from where the arm begins until it divides into two branches (radial and ulnar), and culminates in the hand and fingers.

<h3>What is femoral artery?</h3>

The femoral artery is located in each lower limb, specifically in the anterior and internal part of the thigh, to later become the popliteal and tibial arteries, it transports the blood with oxygen that comes from the left ventricle.

The ionic group coo- on succinate forms bonds with the succinate dehydrogenase
Dmitriy789 [7]

At neutral pH, the ionic group COO- on succinate makes bonds with the active site of succinate dehydrogenase. This bonding is required for succinate oxidation.

<h3>What is succinate oxidation?</h3>

In the Krebs cycle , succinate dehydrogenase catalyzes the oxidation of succinate to fumarate, with the resulting electrons being supplied to respiratory chain complex III to decrease oxygen and produce water.

SDH oxidizes succinate to fumarate during the citric acid cycle. SDH is structurally similar to fumarate reductase, an enzyme that catalyzes the opposite process during anaerobic respiration in bacteria.

what sequence represents the correct order of events for production of the necessary complex molecules after food is taken in by
leonid [27]
Digestion, Absorption, Circulation, Diffusion, Synthesis. 

Digestion begins as soon as you put food in your mouth and begin chewing it, so it is the first step. Absorption happens when food is converted into substances that can be absorbed by your GI tract. Circulation is where those nutrients are circulated in your lymphatic and circulatory system (blood). Diffusion moves oxygen through your blood stream where it gets diffused. S<span>ynthesis converts nutrients that have been diffused and absorbed in your blood. </span>
