The following image of glucose transport by GLUT1 (glucose transporter 1) shows saturation at higher glucose concentrations. What does this infer about the nature of the carrier protein?

Facilitated diffusion, GLUT1 and glucose transport

The carrier protein has a limited number of binding sites.

✅

The carrier protein can transport an unlimited amount of glucose.

❌

The carrier protein is not specific to glucose.

❌

The carrier protein requires ATP for glucose transport.

❌

The carrier protein functions through simple diffusion.

The image shows three red blood cells (RBC) in a scenario similar to one of the experiments you performed in the laboratory. Identify the term that best describes the environment of the RBC indicated by the arrow, using the comparative images to assist you.

Isotonic

Hypertonic

Hypotonic

Tertiary

What is the next step in this process?

Potassium pumped into cell, against its concentration gradient. Sodium-potassium pump

Potassium ions are released into the cell.

✅

The binding of potassium ions changes shape of the protein and results in their release outside the cell.

❌✨

The binding of potassium ions changes shape of the protein and results in sodium ions binding simultaneously.

❌

Phosphorylation leads to a change in protein shape, reducing its affinity for potassium ions, which is released outside the cell.

❌

The protein simultaneously picks up sodium ions and they dislodge the potassium ions inside the cell.

A paper was published that sought to identify the kinds of medical and scientific subspecialties that the Barbie dolls (and a comparison doll group) worked in; and to determine whether these medical professional and scientist dolls met laboratory and clinical safety standards. Which section of the paper would you most likely find the image shown in?
