We all know that life needs energy and that most of the energy for life comes from the sun. We also know that life isn't like a solar panel, so how is solar energy converted into the chemical energy that allows cells to maintain homeostasis?

This lesson describes the need for and basic chemistry of energy. It introduces the molecule ATP and the concepts of oxidation/reduction, especially as they relate to photosynthesis and cellular respiration.
BIO.2 The student will investigate and understand the chemical and biochemical principles essential for life. Key concepts include
d) the capture, storage, transformation, and flow of energy through the processes of photosynthesis and respiration.
• explain how light is the initial source of energy for most communities.
• recognize the equations for photosynthesis and respiration and identify the reactants and products.
• describe the role of ATP in the storage and release of chemical energy in the cell.

Food and Energy- use the book to review chemical bond energy and the amount of energy provided by each of the major organic molecules. #content
ATP - This reviews the structure and function of the molecule ATP, while also revisiting the concepts of autotrophism and heterotrophism.#content #criticalthinking
Organelles of Energy - this reintroduces the structure and function of the chloroplast while also introducing the concept of endosymbiosis, citing the specific evidence that these organelles have their own DNA and ribosomes independent of that of the larger cells. #content
Kingdoms of Energy - students compose a chart that summarizes the main ways that organisms in the different kingdoms of life get their energy .#content

Definition of Energy- the ability to do work
Why do cells need energy? Cell activities in maintaining homeostasis- transport, digestion, production of chemicals, movement...
Autotrophs- produce their own energy
Most autotrophs get their energy from _the sun_, but a small
percentage of them use _chemicals_ to get energy.
Heterotrophs- obtain their energy from others
What molecule is responsible for storing energy? Adenosine Triphosphate
What is the abbreviation? ATP
What are the three parts to the energy molecule? Label the three parts on this diagram.

3. Three phosphate groups (PO4)
When the enzyme ATPase is added to ATP, what happens, what is released? The rate of phosphates released and the amount of energy released increases
How is ADP like a rechargeable battery? It can be recharged back into ATP
