Question

What organelle is present in a cell that actively transports glucose across its membrane?

Answer 1

No specific organelle but the cell membranes of different cells have various protein transporter molecules (GLUT1,2,3,4,5). These transport proteins mediate facilitated transport, that is, they can only transport glucose (or fructose) from areas of high concentration to areas of lower concentration.  The sugar is bound by the protein, a flip-flop mechanism reverses the membrane direction of the sugar-protein complex, the sugar is released and the protein flips around once more to initiate a new cycle.   Transport activity is dependent upon the sugar concentrations and the number of transport proteins in the outer cell membrane.  

Answer 2

Mitochondria will supply the energy for active transport but all living cells must have mitochondria to supply energy. These cells will thus just have MORE mitochondria.
