While using a microscope to examine the cell of an unknown organism, you see that the cell has a nucleus, a cell wall, ribosomes and mitochondria. what kind of organism do you think this cell belongs to?

Molecules like glucose and amino acids are not lipid soluble, so cannot cross the cell membrane by simple diffusion. instead, they are shuttled across by carrier proteins in the membrane from high to low concentration. does this process require energy from the cell? this is an example of what type of molecular movement?
