And a quote "..when a glucose molecule enters the cell phosphorylation is immediate.." But I've been led to believe the cell is a crowded area. Very crowded. Totally crowded.
How can phosphor groups find the glucose molecule 'immediately' ?
You have to consider critically the issues of scale. Molecules are very tiny, they're about as small as you can get and still be a "real thing". There's no "crowd" of cellular organelles keeping molecules apart.
Similar thought when I think of tiny pills ingested by us that effect the whole organism, the whole 200lb of meat or whatever. How can that tiny amount of chemical spread throughout the organism so quickly, permeate everywhere?
They generally don't. They act on a specific part, that in turn effects the entire organism. For example, cardiac medicine works of specific nerves of specific systems, altering feedback for the circulatory system, and that affects the entire organism. Although, a half a gram of antibiotic does in fact end up circulating for a while, but that has an actual affect of making the body fluids hostile to microbe invaders.
My understanding of the molecular, atomic world is miniscule. It only started a couple of weeks ago.
And as I say, I'm not formally a student.
So if you find my questions, observations, understandings annoyingly obtuse, immature, ignorant then please ignore them... I don't mean to pollute the waters...
Keep trying, we're here to help. Try to read some of Issac Asimov's non-fiction books. He can spend a chapter building on topics, just to make one point. Its a good way to learn not only the topic, but to have a respect for the complex interconnectedness science requires.
