Which of the following is NOT an active process by which substances cross the plasma membrane?
A) Pinocytosis
B) Filtration
C) Active transport
D) Phagocytosis
E) All of these are active processes.
Pinocytosis
A form of endocytosis where a cell engulfs liquid containing dissolved substances into a vesicle.
Phagocytosis
The process by which cells engulf and digest solid substances, like bacteria or damaged cell components.
Active Process
involves energy expenditure by the cell to perform tasks such as transporting molecules against a concentration gradient.
- Understand the fundamental concepts of passive and active transport mechanisms within biological systems.
- Determine the function of ATP within cellular transport processes.
