Explain why glucose cannot pass directly through the cell membrans

no

Explanation: Glucose cannot move across a cell membrane via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails. Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.

I hope this explains it If not then I'm sorry :P

not too sure but maybe in the hot springs.

carbon atoms, hydrogen, oxygen, and nitrogen.
