Unicellular organisms consist of one cell only that performs all vital functions including metabolism, excretion, and reproduction. They are responsible for obtaining nutrients, producing energy, and making proteins.
Nucleic acids. They contain a phosphate base and a nitrogen group.
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.
