Question

which of the following is not part of the passive transport process?
atp
concentration gradient
plasma membrane
transporter proteins
question 41 (1 point)
which structure regulates the movement of substances in and out of the cell?
nucleus
ribosome
plasma membrane
endoplasmic reticulum

Explanation:

1. For the first question, passive transport does not require energy in the form of ATP. It relies on concentration gradients, the plasma membrane, and sometimes transporter proteins.
2. For the second question, the plasma membrane is a selectively - permeable barrier that regulates the movement of substances in and out of the cell. The nucleus controls cell activities, ribosomes are for protein synthesis, and the endoplasmic reticulum is involved in protein and lipid synthesis.

Answer:

1. A. ATP
2. C. Plasma membrane
