Explain the characteristics and the mechanism of the secondary active transport then compare and contrast it to the primary active transport.

"Transporters saturate at high concentrations of the transported molecule when all their binding sites are occupied; channels, on the other hand, do not bind the ions they transport and thus the flux of ions through a channel does not saturate." is true or false.

Define cell membrane transport and membrane selectivity.  Explain why the plasma membrane is selectively permeable.  List and discuss which molecules can and cannot cross the membrane and explain why. Discuss why some molecules can cross directly while others require transport proteins.

Discuss the difference in the solute concentration gradient and rate of diffusion between simple diffusion and facilitated diffusion.

compare and contrast the four in tables 1. active and passive transport 2. action membrane potential and resting membrane potential  3. endocrine and exocrine glands

Name at least one similarity and at least one difference between the following (it may help to review the definitions of the terms using the glossary):A. Symport and antiportb. Active transport and passive transportC. Membrane potential and electrochemical gradientD. Pump and transporterE. Axon and telephone wireF. Solute and ion

Match the transport process to the correct description or example. Primary Active Transport is: Group of answer choices transport of glucose out of cell, with its concentration gradient transport of sodium out of a neuron using the sodium potassium pump breaking of a covalent bond to create new molecules transport of large macromolecules into a cell transport of signal molecules out of an endocrine cell transport of a steroid hormone into a cell transport of glucose into a cell, against its concentration gradient import of an entire bacterium into a white blood cell

Match the following statement related to membrane transport processes to the appropriate term or terms: passive transport, facilitated transport, active transport. A transporter (or carrier) protein is necessary. (Select all that apply.) passive transport facilitated transport active transport O O
