<h3><u>Answer</u>;</h3>
B. 2 molecules of ATP are used and 4 molecules of ATP are produced.
<h3><u>Explanation</u>;</h3>
- Glycolysis is the first phase of ecllular respiration that converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
- One glucose molecule produces four ATP, two NADH, and two pyruvate molecules during glycolysis.
- The net products of this process are two molecules of ATP, since four molecules of ATP are produced and 2 ATP molecul;es are used, and two molecules of NADH.

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.
