Energy and Life : Autotrophs and Heterotrophs ADP, ATP. Autotrophs vs. Heterotrophs. Autotrophs Self-energy makers Organisms that make their own food using the sun’s energy (via photosynthesis!!). Heterotrophs Can’t use sun’s energy to make food Obtain energy from foods they consume.
E N D
Autotrophs vs. Heterotrophs • Autotrophs • Self-energy makers • Organisms that make their own food using the sun’s energy (via photosynthesis!!)
Heterotrophs • Can’t use sun’s energy to make food • Obtain energy from foods they consume
What Is ATP? Energy used by all Cells (kind of like the cell’s money) Adenosine Triphosphate Organic molecule containing high-energy Phosphate bonds
Chemical Structure of ATP Adenine Base 3 Phosphates Ribose Sugar
What Does ATP Do for You? It supplies YOU withENERGY!
How Do We Get Energy From ATP? By breaking the high- energy bonds between the last two phosphates in ATP
What is the Process Called? BY HYDROLYSIS (Adding H2O) H2O
How Does That Happen? An Enzyme! ATPase
How is ATP Re-Made? The reverse of the previous process occurs. Another Enzyme is used! By ATP Synthetase
The ADP-ATP Cycle ATP Synthetase ATP-ase
When is ATP Made in the Body? During a Process called Cellular Respiration that takes place in both Plants & Animals
