Homework Answers
Active transport occurs against the concentration gradient and is accompanied by the help of carrier proteins.Energy is used for the movement of Ions or molecules against the concentration gradient.
So here in the options the false statement regarding active transport is c because the sole reason for the transport of molecules or ions is not the concentration gradient .

How does facilitated diffusion differ from simple diffusion? Facilitated diffusion requires ATP Facilitated diffusion requires a solute-specific protein carrier Facilitated diffusion transports solute against its’ concentration gradient Which of the following is TRUE about primary active cell membrane transport? It is a form of transport that requires a protein “pump” It is a form of transport that transports ions and/or solute against their concentration gradient It is a transport mechanism that requires energy released from the splitting of ATP by...

PART A
Correctly order the steps 1-8 as they occur during the transport
of glucose via the phosphotransferase system (PTS):
HPr donates the phosphate group to enzyme IIA (EIIA);
phosphoenolpyruvate is produced as an intermediate of glycolysis;
EI donates the phosphate group to a histidine-rich protein (HPr);
as it enters the cell glucose is phosphorylated by EIIB;
phosphoenolpyruvate donates its high-energy phosphate group to
enzyme I (EI); EIIA passes its phosphate group to Enzyme IIB
(EIIB); glucose is transported across...
