LECTURE 3B: Wilbur and Solar Power

The Lectures NEXT week (Week 4) are longer than usual, so please plan your time for next week accordingly.

FORUM:

Looking at the above results from the Diet Analysis project, many students reported being low in fruits and vegetables. What kind of strategies do you use or could you use to eat more fruits and vegetables ? Note: students also reported being low in dairy, but from my experience you don't need 3 c. of dairy to get the nutrients like calcium that you need. Usually 2 c. is plenty as long as you are meeting the recommendations from the other food groups.
Part 2 of Wilbur says that the plant hooks glucose together to make starch in seeds. What kind of foods can you think of that are seeds that contain starch?

For this lecture, have in front of you the "Wilbur Drawing" and "Your Notes about the Wilbur Drawing" and "Wilbur and Solar Power" in the lecture outline for Chapter 4-1 (which you can print off of moodle).

The "Wilbur Drawing" in your lecture outline is subtitled "How Energy Goes from the Sun to Human Cells". I will be using corn as a specific example of this, but it's what happens in all plants.

It's sort of hard to read the bottom of the "Wilbur Drawing. It says in cells everywhere in body .

I used two books in particular to help me learn more about this process. Both can be found at the LCC Library. Here's one of them.

I chose corn because it's a crop native to the Americas. The illustration on the right shows rice, which would be better used to illustrate this process if we were in Asia.

The other book I used was Isaac Asimov's book Photosynthesis . He was a Russian-born biochemist and writer who died an American in 1992.

Isaac Asimov is the author of 300 books, many of them science fiction.

5 steps of the Wilbur Drawing

Photosynthesis

Where is the Wilbur Drawing showing photosynthesis taking place?
Making starch in the plant. The plant can bond more than 1000 molecules of glucose together to make starch.

Where in the Wilbur Drawing does it show starch being made in the plant?
Digestion. The starch in the popcorn is digested down to individual glucose molecules. Where is the Wilbur Drawing showing starch enzymes being present? You should see TWO places.
Absorption & Transport. The individual glucose molecules are absorbed from the small intestine into the bloodstream which transports them to cells everywhere.
Cellular Respiration- Inside cells everywhere, the glucose is broken apart, releasing its energy. Only then does Wilbur get any energy out of the popcorn.

The two videos below will explain these 5 steps in more depth.
