ADP, ATP and Cellular Respiration

Engage: Let’s Recap Photosynthesis Plants absorb sunlight and use its energy to grow directly. Autotrophic plants use chloroplasts, and the process of photosynthesis, to capture the energy from sunlight and store it by creating sugar (glucose) molecules. 1. Write out the chemical equation for photosynthesis. Using the magazines supplied, cut out pictures/symbols that can represent the reactants and products of photosynthesis.

However… It is important for you to realize that photosynthesis alone can not sustain life. Plants, or other living things, can not stay alive if this was all that happened. Remember, glucose is like a storage house for energy, storing the chemical energy obtained from the sun. How is all of this energy released from storage???

EXPLORE: CELLULAR RESPIRATION Respiration releases the chemical energy stored in glucose, which is used by the cells to carry out their life activities (growing, moving, etc.). 2. Create a labeled diagram showing how photosynthesis and respiration are related using pictures cut out from a magazine.

Sunlight (radiant energy) is Transformed through the process of Photosynthesis in Green Plants Transforming the radiant energy into GLUCOSE (chemical energy) which can be Respired by Plants & Animals to Transform chemical energy Into other forms Required to continue living.

RESPIRATION – Respiration is NOT the same as what we call breathing! – Respiration is a chemical reaction… 3. Write out what you think the equation for respiration looks like.

What Is ATP? Energy used by all Cells Adenosine Triphosphate Organic molecule containing high- energy Phosphate bonds

Chemical Structure of ATP 3 Phosphates Ribose Sugar Adenine Base Draw This !

What Does ATP Do for You? It supplies YOU with ENERGY!

How Do We Get Energy From ATP? By breaking the high- energy bonds between the last two phosphates in ATP

When is ATP Made in the Body? During a Process called Cellular Respiration that takes place in both Plants & Animals

Overall Equation for Cellular Respiration 6CO 2 + 6H e ATP’s C 6 H 12 O 6 + 6O 2 YIELDS

Where Does Cellular Respiration Take Place? It actually takes place in two parts of the cell: It actually takes place in two parts of the cell: Glycolysis occurs in the Cytoplasm Krebs Cycle & ETC Takeplace in the Mitochondria Krebs Cycle & ETC Take place in the Mitochondria
