Diastole is the ________ phase of the cardiac cycle.
STatiana [176]
Diastole is the relaxation phase of the cardiac cycle. It is the normal rhythmic dilation of the heart's valves. During this time, the valves start to gather blood inside of their chambers. There are two types of diastole that occur in the heart, and they are:

1. Ventricular diastole - this is the period where the ventricles are filling and relaxing. 
2. Atrial diastole - the period in which the atria are relaxing. 

This is a continuous cycle that occurs in the heart the moment a person is conceived until the person meets his/her death.

Ouabain is a specific inhibitor of the active transport of sodium ions out of the cell and is therefore a valuable tool in studi
Kay [80]

Answer:

1. Part A: No

2. Part B: Yes

3: Part C : Yes

4: Part D : No

Explanation:

1) Part A: Facilitated diffusion of glucose into a muscle cell:

No; sodium ion co - transport is required for active transport of glucose but not for facilitated diffusion of glucose

2) Part B: Active transport of dietary phenylalanine across the intestinal mucosa:

Yes; co - transport of sodium ions drives the inward movement of amino acids and can only occur if sodium ions are actively pumped back out again.

3) Part C: Uptake of potassium ions by red blood cells:

Yes; uptake of potassium ions can occur only via a pump that couples the inward pumping of potassium ions to the outward pumping of sodium ions.

4) Part D: Active uptake of lactose by the bacteria in your intestine

No; active uptake of sugars and amino acids in bacteria is driven by a proton gradient.

The sodium-potassium pump is involved in active transport that moves 3 sodium ions from the cell for every 2 potassium ions it m
Ugo [173]

Answer:

The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.

Explanation:

You have to think of it as outside vs inside the cell.

Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration.  Energy keeps the ions going from the way they would naturally happen.
