The correct answer is option (h) the breathing rate to supply more oxygen to cells for the release of energy.

Breathing refers to the process of inhaling oxygen and exhaling carbon dioxide from the lungs. A normal breathing rate at rest is around 15 breathes per minute which is significantly increased to 40 -50 breathes per minute during vigorous activity or excercise.

During exercise, the breathing rate, pulse rate and lactic acid levels increase in the human body. Muscle cells have an increased need for energy and heart pumps more oxygen to the muscle cells to meet the requirement. Breathing rate increases to supply more oxygen to the muscle cells which is required for the oxidation of the glucose, release of more energy and to get rid of the carbon dioxide.

_The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of
Hoochie [10]

Complete question:

The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K

  • True
  • False

Answer:

TRUE

Explanation:

The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.

Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.

Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.

K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.

Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

Which of the above molecules would be least soluble in water?<br><br>(See attached image)​
weqwewe [10]

C

Explanation:

Molecule C would be least soluble in water because it is not a polar compound/molecule. It also lacks any unit that can combine with water to form a good hydrogen bond.

  • The general rule of solubility is that like dissolves likes.
  • Polar molecules will only dissolve in polar solvent.
  • Water is a polar solvent with hydrogen bonds in them.
  • Hydrocarbons typically have weak london dispersion forces between them and they are not polar.
  • Other compounds have functional groups that can form hydrogen bond with water.

Triggering of the muscle action potential occurs after
vekshin1

Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.

An action potential is an electrical signal that travels along the cell membrane as a wave.

This action potential (muscle action potential) drives the contraction of muscle fibers.

When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.

Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.
