Study Guide: Cell Respiration and Cell Membranes

To-Do Date: Sep 11 at 11:59am

Cartoon

Its a cliché to call the mitochondria the powerhouse of a cell? In this cartoon, they show a mitochondria lifting heavy weights like it is a powerhouse weight lifter ( but clearly not a body builder- way too lumpy and bumpy!) What does the mitochondria do in real life? What is the ''power'' that it is producing?

We will continue our work to understand diabetes. In order to do that, we have to think about many different scales at the same time( cells, molecules, organs, etc) Here is a flowchart that helps me to organize my thinking on the subject. This week we are going to focus on the part of the flow chart outlined in red: from the digestive system to the cells.

Learning Objectives : 

by the end of the week you will be able to: 

• Visualize the absorption of subunits from the small intestine all the way to their delivery via the blood and absorption across the cell membrane
• Identify and draw the basic structure of a cell membrane, including the arrangement of the phospholipids, location of membrane proteins and cytoskeleton
• Explain how the structure of the membrane determines which type of molecules can cross the cell membrane and by what methods.
• Identify the crucial role of cell membranes as the connector between cells and other cells, organs, blood, including the special role of cell membrane proteins. 
• Identify the different uses a cell can have for subunits: 

• Identify the importance of  cell respiration: including 
  • • • What are the ingredients?
      • What are the products?
      • Why is ATP such an important molecule?
