The cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
true
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?
What transport where molecules are actively leaving the cells?
When molecules are actively leaving and entering cells, this process is called active transport. It is the only way of transportation that involves energy.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
Explain the difference between active transport and facilitated transport?
facilitated transport -this type of division occurs according to concentration gradient but it involves carriers like permeases ,Translocase etc. active transport- it takes place against their concentration gradient .carrier molecule which occur in P.M. become attached to transport &a carrier transport complex is formed.
What involves two active transport processes coupled together?
Cotransport
Does active transport require transport proteins?
Yes, active transport requires carrier proteins in order to function. These require ATP to carry things in and out of the cell.
The cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
true
Active transport requires energy because it usually involves the movement of what substances?
Molecules
Is it true that the cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
yes
How does facilitate transport differ from active transport?
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
What are a series of carrier proteins?
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
The cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier. true or false?
true
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?
What is a good sentence for Active Transport?
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
What type of molecule movement involves the use of ATP?
Active transport. This is movement of molecules against the concentration gradient.
Is osmosis an example of active transport?
no, Osmosis is the movement of water from a higher water potential to a low water potential. This requires no energy. Active transport requires energy and it involves substances moving from a lower concentration to a higher.
