Question
Transport of glucose in the gut and kidneys tubules are examples of active transport.Question 7Answera.Trueb.False
Solution
The statement is true.
Here's a step-by-step explanation:
-
Active transport is a process that moves ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
-
Glucose is a crucial source of energy for the body's cells. In the gut, after the food we eat is broken down into smaller molecules including glucose, it needs to be absorbed into the bloodstream so it can be transported to the cells where it's needed.
-
This absorption happens in the small intestine, where glucose is actively transported across the intestinal cell membrane into the bloodstream. This process requires energy because it's moving glucose from a lower concentration in the gut to a higher concentration in the blood.
-
Similarly, in the kidneys, glucose is filtered out of the blood and into the urine in the kidney tubules. However, the body doesn't want to lose all this valuable glucose, so it's actively transported back into the bloodstream from the urine. Again, this requires energy because it's moving glucose from a lower concentration in the urine to a higher concentration in the blood.
So, the correct answer is a. True.
