Question

question 3
a bacterium will construct different proteins to metabolize the sugars lactose or glucose, depending on which one it detects in the outside environment. what part of the bacterium allows it to recognize different substances in the outside environment?
o lysosomes
o nucleus
o endoplasmic reticulum
o cell membrane

question 4
which of the following is a type of active transport which involves moving larger materials into a cell?
o simple diffusion
o exocytosis
o endocytosis
o facilitated diffusion

Explanation:

Analyze Question 3

Using the Cell Membrane Function knowledge point

Bacterial cells interact with their external environment primarily through the cell membrane, which contains receptor proteins that detect external substances like sugars.

Analyze Question 4

Using the Active Transport and Exocytosis knowledge points

Active transport requires energy to move substances. Moving larger materials into a cell is a form of active bulk transport known as endocytosis, whereas moving them out is exocytosis.

Answer:

Question 3

• O lysosomes
• O nucleus
• O endoplasmic reticulum
• O cell membrane (Correct answer)

Question 4

• O simple diffusion
• O exocytosis
• O endocytosis (Correct answer)
• O facilitated diffusion
