Energy on a cell web quest

1. Introduction:

Every living thing requires energy to live. In this web quest you will learn and review the processes in which the animal and the plant cell transform different types of energy for their use. The organelles chloroplast and mitochondria are involved in a series of biochemical reactions that make this possible.

2. The task:

In this WebQuest you will fin a list of questions that you need to answer correctly. For each question you will find an specific Internet address that you will have to visit to find out the proper information. Send your answer sheet (create a WORD document) to the address vanevet77@hotmail.com.

3. Process:

Instructions: Answer the following questions by going to the specific Internet address below each of the questions.

• Questions:

1. What is the structure of the ATP molecule. Comment about this molecule ability to store and release energy and include a diagram (picture) of the ATP, ADP and AMP molecules.

   Ø Completeness………………………………………………........20 points
   TOTAL of….........................................................100 points

5. Conclusion:

By now you should now the processes of photosynthesis and cellular respiration. You should know how this processes are interconnected to each other and their importance for living things and the Earth in general. Hope you found this information useful and that it helped you further understand the job of the mitochondria and the chloroplasts organelles.
