Answer:
The correct answer is a acyl-carnitine readily cross the mitochondrial inner membrane but the acyl CoA do not.
Explanation:
Fatty acids are activated to form fatty acyl CoA by the help of ATP and CoA SH.But the so formed Acyl CoA cannot cross or pass the inner mitochondrial membrane to enter the mitochondrial matrix to initiate beta oxidation of fatty acid.
To overcome this problem fatty acyl CoA is converted to acyl carnitine and the so formed acyl carnitine readily crosses the inner mitochondrial membrane and enters the mitochondrial matrix.
It is not a molecule because the bond that holds NaCl together is an ionic bond
Answer:
The correct answers are option 2, 4 and 6
Explanation:
2-The T tubules are the extensions of the cell membrane that goes deep into the center of the middle of the skeletal and cardiac muscles and are in close contact with the sarcoplasmic reticulum.
These tubes plays 2 vital functions in connecting an action potential to muscle contraction. T tubules causes the action potential from the plasma membrane into the interior of the muscle cell through voltage-gated Na+ and K+ channels.
An action potential causes the opening and closing of Calcium channels in the sarcoplasmic reticulum. The resulting change in cytosolic Ca2+ concentration triggers contraction of the myofibrils.
The T tubules play two important roles in linking an action potential to muscle contraction.
