Hello!
So I'm confused as to how I got this question wrong:
Which of the following would be allowed to cross the cell membrane without the aid of an accessory protein?
a.) Glucose
b.) Glycine
c.) Ketone Bodies
d.) Triglycerides
My thoughts:
a.) No. Glucose is obviously not the answer because it is a larger molecule and a lot of the time it uses Na+ to get into cells or other forms of transport.
b.) Best answer. Small amino acid, but polar and may not be able to cross the biphospholipid...
