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.
Answer:
Why are molecules such as valinomycin effective at transporting ions across the membrane?
Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.
Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.
Explanation:
Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
