Essential nutrients move through a cell membrane by both passive transport and active transport. Which of the following correctly describes the transport of materials across a cell membrane?

This question lacks options, the options are:

A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.

B). Passive transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.

C). Active transport moves nutrients from areas of high concentration to areas of low concentration without the use of chemical energy.

D). Passive transport moves nutrients from areas of low concentration to areas of high concentration without the use of chemical energy.

The answer is A

Explanation:

Transport of materials across a cell occurs via passive transport or active transport depending on whether energy input is required or not to facilitate the movement.

- Passive transport is the transport of materials e.g nutrients from areas of high concentration to areas of low concentration i.e down a concentration gradient, without the use of chemical energy (ATP).

- On the other hand, active transport requires chemical energy (ATP) to move nutrients from areas of low concentration to areas of high concentration i.e against concentration gradient.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
