The anatomy of the intrinsic conduction system causes contraction of the ventricles to begin at the apex and move superiorly. Wh

y is this important? The anatomy of the intrinsic conduction system causes contraction of the ventricles to begin at the apex and move superiorly. Why is this important? because the Purkinje fibers conduct action potentials away from the heart apex because the AV bundle is the only electrical connection between the atria and the ventricles

<h2>Blood is forced upward and toward</h2>

Explanation:

  • In the cardiovascular cycle, the autonomous withdrawal and unwinding of heart cells are facilitated through the movement of the heart's characteristic conduction framework and by cell-to-cell correspondence by means of the hole intersections in the myocardial cells themselves.  
  • The natural conduction arrangement of the heart comprises of nodal tissue, whose specific cells have both apprehensive and solid qualities. Nodal tissue is restricted in explicit areas of the heart.

When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl COA. Predict how many ATP can be made
IgorC [24]

Answer:

12 molecules of ATP can be made from one molecule of acetyl CoA.

Explanation:

If one molecule of acetyl CoA enter TCA cycle then it result in the formation of 3 molecules of NADH,1 molecule of FADH2 and 1 molecule of GTP that is equivalent to 1 molecule of ATP.

                        Now the reducing equivalent such as NADH and FADH2 enters electron transport chain and get oxidized to regenerate NAD+ and FAD along with ATP. 1 molecule of NADH produces 3 molecules of ATP whereas 1 molecule of FADH2 produces 2 molecules of ATP.

               So that net gain of ATP is given below

3 molecules of NADH = 9 molecules of ATP

1 molecule of FADH2 =2 molecules of ATP

1 molecule of GTP = 1 molecule of ATP

As a result total 12 molecules of ATP is by the oxidation of 1 Acetyl CoA  by TCA cycle .

Lerok [7]
The answer is A.
If the bicipe muscle contracts it will bring the forearm up because the insertion of this muscle is  in the forearm.
One of the functions of this muscle is flexing the elbow, which would result in the action i already mentioned.
It couldn't be B, because that would be the work of another muscle, the triceps.
