The coronary circulation is being researched in both healthy and pathological conditions. They conduct blood flow and pressure measurements (blue circle) in one of the epicardial coronary arteries of a laboratory animal model with heart function that is comparable to humans. After simulating a 60% atherosclerotic stenosis in the artery with a clamp, the flow and pressure distal to the lesion are once again measured. After reaching steady state, which of the following modifications is most likely to be seen?
Sodium Ions
Positively charged ions (Na+) essential for various physiological processes in the body, including nerve impulse transmission and muscle contraction.
Enzyme-Linked Receptors
Transmembrane proteins with a hormone-binding site outside the cell and an enzyme site inside the cell.
Tyrosine Kinase
An enzyme that phosphorylates the tyrosine part of proteins.
G Protein
A group of proteins that act as molecular switches across cell membranes, involved in transmitting signals from stimuli outside the cell.
