Welcome back!! Happy New Year!!! Aim: How does the cell get energy to fuel all of its life processes? DO NOW: Why do we need energy? Think of at least 2 examples! Reminder- if you choose to do test corrections- I need them this week !!! HW: List 5 things you did today that required ATP (ENERGY) - write or draw your answers 

Creating Energy in a Cell

Why do we need energy? Organisms are made of cells which need energy to work, move & grow.

How do living things get energy? Autotrophs Trap energy from the SUN to make food (glucose) Heterotrophs eat other animals & plants to get energy

Types of Energy Light Heat Wind Electrical

Energy can be changed from one form to another

Food Energy  Cell Energy (Organic Compounds ) Cells can’t run directly on food energy Food Energy  Cell Energy (Organic Compounds )

Food Energy  Cell Energy (Organic Compounds ) ATP Energy cells run on is called ****ATP**** Food Energy  Cell Energy (Organic Compounds ) ATP

Energy Summary:

How Much ATP Do Cells Use? It is estimated that each cell will use10,000,000 molecules of ATP ….. Every second!!

ATP! Cell Respiration - ALL THE POWER the cells need comes from ATP  Process that creates usable energy (ATP) for cells. ATP! ALL THE POWER the cells need comes from ATP 

Chemical Equation for Cellular Respiration: oxygen + glucose carbon dioxide +water + ATP (energy) O2 + C6H12O6 CO2 + H2O + Energy Waste

ATP gives the cell a big burst of energy to power all of its life processes

State Standards 5.1d In all organisms, the energy stored in organic molecules may be released during cellular respiration. This energy is temporarily stored in ATP molecules. In many organ- isms, the process of cellular respiration is concluded in mitochondria, in which ATP is produced more efficiently, oxygen is used, and carbon dioxide and water are released as wastes.
