Question

During active transport in the neuron, the outside of the cell is _________________ and the inside is _______________.

negative, positive

In active transport, _____________ provides the energy to move molecules against their concentration gradient.

adenosine triphosphate

________________ proteins can change shape when moving substances across the membrane.

Proteins that can be open or closed, based on different conditions, are called ___________.

gated

Tunnels that allow charged ions to move easily across the plasma membrane without the use of energy are called ____________________.

carbohydrate chains

____________ and ____________ make it easier for molecules to move across the plasma membrane.

Explanation / Answer

Ans:

1) During active transport in neurons, the outside of the cell is more positive and the inside is more negative.

2) In active transport, adenosine triphosphate provides the energy to move molecules against their concentration gradient.

3) Carrier proteins can change shape when moving substances across the membrane.
Proteins that can be open or closed, based on different conditions are called gated.

4) Tunnels that allow charged ions to move easily across the plasma membrane without the use of energy are called channel proteins.

5) Small and no charge make it easier for molecules to move across the plasma membrane.
