How are substances and structures transported within the cell?
Substances and structures are transported within the cell through processes such as diffusion, facilitated diffusion, active transport, and vesicular transport. Diffusion involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion uses protein channels to help substances across the cell membrane. Active transport requires energy to move molecules against their concentration gradient. Vesicular transport involves the formation of vesicles that transport substances within or out of the cell.
During active transport substances move from regions of what?
in active transport, where do molecules always go
Substances outside a cell are transported into the cell by vesicles during?
Substances outside a cell are transported into the cell by vesicles during endocytosis. This process involves the formation of a vesicle that engulfs the particles or molecules outside the cell, then fuses with the cell membrane to bring the contents into the cell.
This transport process moves substances agaisnt a concentrating gradient and requires energy?
active transport
Is plasmolysis an example of active transport?
Osmosis is the tendency of fluid to pass through a semi-permeable membrane until there is an equal concentration of fluid on each side of the membrane. The fluid in not transported, movement is self induced

The use of energy to move substances across a cell membrane describes?
Active transport, which requires energy in the form of ATP to move substances against their concentration gradient across a cell membrane. This process involves specific protein pumps that bind to the molecule being transported, consuming ATP to change conformation and move the molecule across the membrane.
Does active transport move substances against the concentration gradient?
Yes, active transport moves substances against the concentration gradient.
Does active transport move substances against their concentration gradient?
Yes, active transport moves substances against their concentration gradient.
What is active transport across the cell?
Active transport simply means the transport of substances against the concentration gradient.In this transport,ATP is utilised.
What is the purpose of active transport?
Active transport expends energy to move substances against a concentration gradient.
During active transport substances move from regions of what?
in active transport, where do molecules always go
How do carrier proteins recognize substances to transport in active transport?
substance to pass
How do carrier protein recognize substances to transport in active transport?
substance to pass
What is the transport of substances from the outside to the inside of a cell by a vesicle?
Vesicular active transport
A cell must expend energy to transport substances using?
A cell must expend energy to transport substances across its membrane against their concentration gradient, a process known as active transport. This energy is usually provided by ATP, the cell's main energy currency.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
