Lecture Topic For Examination #2

Releasing Energy - Cellular Respiration

Background:

Cellular respiration is essentially the opposite of photosynthesis. In photosynthesis we say how energy in the form of electromagnetic radiation was converted in the light dependent and light independent reactions to a form of energy that living organisms can use - chemical energy.

Cell respiration is the process by which living organisms are able to harvest the energy which is trapped in the bonds that are holding energy rich molecules together.

The examination will have one major full-page problem which will ask you to name and spell correctly the names, and tell the number of carbon atoms, of all of the compounds in cell respiration which are covered in lecture.

Reading Assignment:

Read Chapter 6 in the textbook: Biology:Concepts & Principles.

Refer to page 149 - Chapter Summary in Survey of Biology Lecture Notes - for the terms and key points you need to know. The Key Points are your guide to success in the course because they focus your attention on those topics upon which you need to concentrate your study to be optimally prepared for the upcoming examination.

Also study the references to the textbook which are indicated in the Survey of Biology Lecture Notes.

Lab Manual Assignment:

Crossword for Chapter 11 due upon arrival.

Study Group Activities:

Quiz everyone in the group on the flashcards labeled "Cellular Respiration." Try to complete this before the lecture called "Releasing Energy - Cellular Respiration."

Interactive Study Partner CD ROM:

CHAPTER 6 - HOW CELLS HARVEST CHEMICAL ENERGY

Food contains chemical energy, and cells obtain that energy by "burning" food molecules. These activities bring to life cellular respiration, the process that captures the energy in food.

Activities:
6A Overview of Cellular Respiration
6B Glycolysis
6C The Krebs Cycle
6D Electron Transport and Chemiosmosis
