To help students prepare for this important Unit Test, students received a three-page Study Guide for this test in class on Nov. 27th, and Mr. Hatfield wants very much for students to use this Study Guide over the weekend to prepare for their test on Tuesday!
The Study Guide, in turn, will form the basis of a Study Session to be held after school on Monday, Dec. 3rd, between 3:15 and 5:30 in Room N-63. Students who attend and participate will earn EXTRA CREDIT in the course, get their questions based on the Study Guide answered and (if they stay to the end) important hints about the test itself.
Mr. Hatfield also reminds Biology students that they should be bringing their Composition Books, with their completed Cornell Notes inside. Students whose Notes are completed, after all, are allowed to use them on the Unit Test!
Speaking of the test itself, Mr. Hatfield wants to remind ALL students that additional time to complete the non-SCANTRON portion of the test is available both during LUNCH and AFTER-SCHOOL. No student should fail to use all of the time available to them to attempt EVERYTHING on the test.
As if Monday's Study Session wasn't enough, Mr. Hatfield is also extending an opportunity for additional support to be held on Saturday, Dec. 1st, in Room N-63, between 8:45 and 11:30. Students who have been assigned or who have requested to attend Saturday School must show up promptly at 8:45. They will be focused on doing activities that will earn them EXTRA CREDIT in the course and also help prepare them for Tuesday's exam.
Students who have been assigned Saturday School but who fail to attend without a parent contact may be referred to Administration.

You'll find links to the most current set of Notes down here. The first Power Point contains an outline of photosynthesis, relating it to the 'Great Circle' of chemical reactions that all living things participate it (autotrophs and heterotrophs!), reactions which recycle the raw materials that life requires. Much of this material is covered in the first two sections of Chapter 8 in the Dragonfly Book.
The Power Point for Photosynthesis, Part I, is available here.
Photosynthesis, Part II provides much more detail about the light reactions, photosystems, the proton pumps that use the enzyme ATP synthase, the electron transport chains that help power those pumps. There is less detail about the 'dark reactions' of the Calvin cycle and other material which is not explicitly part of the state standards. This is covered in Section 8.3 of the Dragonfly Book.
You can download Photosynthesis, Part II here.
A third Power Point is somewhat brief, but has many helpful animations that help describe and explain the structure and function of ATP (adenosine triphosphate), the main energy-carrying molecule used by living things.
The fourth and final Power Point in this unit contains information about cellular respiration, including glycolysis (which takes place in the cytoplasm) and the Krebs Cycle (which takes place in the matrix of the mitochondria). The electrons produced in the Krebs Cycle move through the inner membrane, or cristae, of the mitochondria. The motion of these negatively-charged particles attracts protons (H+), and eventually a high concentration of protons within the membrane is available to drive 'proton pumps' that power an enzyme, ATP synthase, leading to the production of more ATP:
