4.1 Chemical Energy and ATP

2.1 Atoms, Ions, and Molecules

  • Set up Cornell Notes on pg. 41

  • Topic: Chemical Energy and ATP

  • Essential Question:

    How are some organisms able to survive without sunlight and photosynthesis?

  • Don’t forget to add it to your T.O.Contents!

How are some organisms able to survive without sunlight and photosynthesis?

Key Concept: All cells need chemical energy


Table talk
Table Talk

  • Do energy drinks or power bars do something different from any other foods you eat? If so, what do they do? What causes them to do this?

They may contain certain types of carbohydrates that can be used more quickly and so supply energy faster.

Note: An energy bar provides no more energy than a bagel or banana

1.f- Know that useable energy is captured from sunlight by chloroplasts and is stored through the synthesis of sugar from carbon dioxide.


KEY CONCEPT All cells need chemical energy.


*The cells of ALL organisms need chemical energy for ALL of their processes.

  • Plants absorb energy from sunlight and some of that energy is stored in sugars

    • Cells break down sugars to produce usable chemical energy for their functions

      • Without organisms that make sugars, living things on Earth could not survive!


The chemical energy used for most cell processes is carried by adenosine triphosphate aka ATP.

  • ATP transfers energy from the breakdown of food molecules to fuel all cellular functions

Remember from Ch. 2: Energy is released when bonds break!

  • When the unstable 3rd phosphate breaks off- A blast of energy is released!

  • Adenosine diphosphate aka ADP is a lower-energy molecule than ATP with only 2 phosphates. ADP is changed into ATP when a phosphate group is added

    • A large amount of protein is needed to do this!



Foods that you eat by do NOT contain ATP.

  • First the food must be digested, which breaks down food into smaller molecules that can make ATP.

    * The number of ATP molecules that are made during the breakdown of food is related to the amount of calories.


Carbohydrates are the molecules by most commonly broken down to make ATP.

adenosine

triphosphate

tri=3

adenosine

diphosphate

di=2

  • not stored in large amounts

  • up to 36 ATP from one glucose molecule

ATP

ADP


  • 80 percent of the energy in your body is stored in fat

  • Proteins are least likely to be broken down to make ATP.

  • amino acids not usually needed for energy

  • about the same amount of energy as a carbohydrate

(Fats)


Point to ponder
Point to Ponder by

  • If we get our energy from food….

    • Where does our food get its energy?

      • Hint: Your food is probably a plant or animal

  • Plants get their energy from the sun

  • Animals get their energy from the plants they eat

  • Ipso Facto: We all get our energy by using sunlight!

PHOTOSYNTHESIS!!!!!!!!!!!!!!!!!


A few types of organisms do not need sunlight and photosynthesis as a source of energy
A few types of organisms do not need sunlight and photosynthesis as a source of energy.

  • Some organisms live in places that never get sunlight.

  • In chemosynthesis, chemical energy is used to build carbon-based molecules.

    • uses chemical energy instead of light energy
