Solution
The processes that use ATP either directly or indirectly are:
-
Exocytosis: This process uses ATP directly. It is the process by which cells transport molecules out of the cell by expelling them in an energy-dependent process.
-
Cotransport: This process uses ATP indirectly. It is a mechanism in which a single ATP-powered pump that transports a specific solute can indirectly drive the active transport of several other solutes.
-
Active transport: This process uses ATP directly. It is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
-
Pinocytosis: This process uses ATP directly. It is a mode of endocytosis in which small particles are brought into the cell, forming an invagination, and then suspended within small vesicles.
-
Phagocytosis: This process uses ATP directly. It is the process by which a cell uses its plasma membrane to engulf a large particle, giving rise to an internal compartment called the phagosome.
-
Autophagy: This process uses ATP directly. It is the natural, destructive mechanism that disassembles, through a regulated process, unnecessary or dysfunctional components allowing the orderly degradation and recycling of cellular components.
-
Endocytosis: This process uses ATP directly. It is a form of active transport in which a cell transports molecules into the cell by engulfing them in an energy-using process.
-
Receptor-mediated endocytosis: This process uses ATP directly. It is a process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of the plasma membrane.
The processes that do not use ATP either directly or indirectly are:
-
Facilitated diffusion via a carrier protein: This process does not use ATP. It is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins.
-
Facilitated diffusion via a channel protein: This process
