My name is Ann [436]

Answer: Myocardial infraction can be defined as the condition which is caused due to absence of oxygen in major parts of the heart.

This also causes ischemia which occurs primarily and myocardial infraction occurs secondarily to this.

When, oxygen and nutrients from the blood reaches to the area which was deprived of oxygen results in inflammation and oxidative damage.

This is caused due to induction of oxidative stress rather than the normal functioning of the body.

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?

gladu [14]

Answer:

$\boxed {\boxed {\sf A. \ Channel/Transport \ proteins}}$

Explanation:

The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.

Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.

So, salt, water, and fats do not contribute to the movement of larger molecules, but <u>channel or transport proteins do and choice A is correct. </u>
