Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.

Based on this information, what type of transport is used for glucose in blood and intestinal cells?

A.
Both blood and intestinal cells take in glucose by passive transport.
B.
Blood cells take in glucose by active transport and intestinal cells take in glucose by passive transport.
C.
Blood cells take in glucose by passive transport and intestinal cells take in glucose by active transport.
D.
Both blood and intestinal cells take in glucose by active transport.

Answers

Answer 1

Both blood and intestinal cells take in glucose by passive transport. Thus, the correct option is B.

What is facilitated diffusion?

A transport protein found in the plasma membrane facilitates diffusion, which is the passive movement of things like biological molecules or ions across a plasma membrane. Chemical energy is neither utilized nor required because compounds are moved from higher to lower concentrations.

Glucose is absorbed by the mechanisms of facilitated diffusion or passive transport across the membrane of red blood cells. The sugar glucose is transferred by active transport from the gut into intestinal epithelial cells.

During isovolumetric phases of the cardiac cycle, a. The atria are contracting and all heart valves are closed. b. All heart valves are closed. c. The ventricles can only be relaxing. d. The atria are contracting. e. Blood is being ejected into the aorta.

Answers

During isovolumetric phases of the cardiac cycle, the atria are contracting.

What happen in isovolumetric phases of the cardiac cycle?

The isovolumetric contraction occurs in isovolumetric phase that causes left ventricular pressure to rise above atrial pressure. This leads to opening of aortic valve at the end of isovolumetric contraction when left ventricular pressure exceeds aortic pressure.

So we can conclude that during isovolumetric phases of the cardiac cycle, the atria are contracting.

The North Atlantic right whale was classified as an endangered species in 2015. A major cause of death for these whales is collisions with shipping vessels. Several measures have been enacted to prevent such collisions in regions with a high abundance of right whales. In 2002 and 2006, shipping vessel lanes were rerouted around some of these regions. In 2008, speed restrictions were placed on the shipping vessels that were permitted to travel through these regions.

The graph below shows the estimated abundance of North Atlantic right whales from 1990 to 2015. The years in which these measures were enacted are marked on the graph.
