Answer:
D) Glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.
Explanation:
Glucose is a polar, large, and hydrophilic molecule that cannot easily diffuse the cell membrane. It moves across the membrane through a mechanism known as <u>facilitated diffusion</u>. In this process, a carrier protein attaches itself to glucose molecule and transport it without any use of ATP. Instead, the movement is driven by concentration gradient. An example is the diffusion of glucose in red blood cells.
Well, it depends but adults can weigh up to 420,000 pounds
Answer:
This process would be the one truly responsible for the "evolution" of mitochondria and chloroplasts as we know them from their prokaryotic ancestors. The cell process that would have initiated endosymbiosis is endocytosis; the process of taking things inside the cell
I think it’s false but jsjs
