Question

select the single word in each sentence to make it correct.

1. up to a point, (click to select) solute concentration increases transport rate.
2. at some point, all carriers are (click to select) and solute cannot be moved any faster.
3. at this point, the addition of more solute (click to select) increase the amount of solute being transported.
4. this point is referred to as the (click to select) maximum.

Explanation:

To solve this, we analyze each sentence based on concepts of solute transport (likely related to facilitated diffusion or active transport with carriers):

Sentence 1

In transport processes (e.g., facilitated diffusion), increasing solute concentration (up to a point) increases the transport rate, as more solute molecules are available to bind to carriers.

Sentence 2

When all carriers are saturated (bound to solute), no more solute can be moved faster, as there are no free carriers left to bind additional solute.

Sentence 3

Once carriers are saturated, adding more solute cannot increase the transport rate, because the carriers are already working at maximum capacity.

Sentence 4

This saturation point is the transport maximum (the maximum rate at which solute can be transported by the carriers).

Answer:

s:

1. increasing
2. saturated
3. cannot
4. transport
