Does active transport move molecules down or against the concentration gradient?
Against
the
concentration
gradient
View source
What is required for active transport to occur?
Energy from the hydrolysis of
ATP
View source
Where is ATP produced?
In the
mitochondria
View source
What type of proteins are involved in active transport?
Carrier proteins
View source
What happens to ATP during active transport?
It is
hydrolysed
into
ADP
and
phosphate
to release energy
View source
What is the main difference between active transport and facilitated diffusion?
Active transport requires
ATP
but facillitated diffusion is passive
View source
Define active transport.
The movement of molecules and ions from an area of lower concentration to an area of higher concentration (against the
concentration gradient
) using
ATP
and
carrier proteins
.
