Explanation / Answer

Answer:

1. [a] endoplasmic reticulum.

[b] ribosomes

[c] smooth endoplasmic reticulum

[d] carbohydrates

[e] golgy apparatus

2. [D] cell.

3 .

1 Movement from low concentration to high concentration that needs energy from ATP-active transport

2 Movement from high concentration to low concentration - diffusion

3 Movement of water from high concentration to low concentration-osmosis

4Movement from high concentration to low concentration through the use of protein carriers - facilitated diffusion

4. [B] smooth endoplasmic reticulum

5.[d] ribosome

6.[a] Enzymes lower the activation energy speeding up chemical reactions.

1 Movement from low concentration to high concentration that needs energy from ATP-active transport

2 Movement from high concentration to low concentration - diffusion

3 Movement of water from high concentration to low concentration-osmosis

4Movement from high concentration to low concentration through the use of protein carriers - facilitated diffusion

4. [B] smooth endoplasmic reticulum

• It helps in detoxification process and found in the cell of liver.

5.[d] ribosome

• Endomembrane system consist of golgybody, endoplasmic reticulum,nuclear envelope, nuclear membrane among others.

6.[a] Enzymes lower the activation energy speeding up chemical reactions.

• They are made up of protein and act as bio catalyst in living system.
