Cellular Respiration Overview • Transformation of chemical energy in food into ATP (chemical energy cells can use) • These reactions proceed the same way in plants and animals. Process is called cellular respiration • It happens in the mitochondria
The equation= Overall Reaction: C 6 H 12 O 6 + O 2 → CO 2 + H 2 O Glucose+ Oxygen Carbon Dioxide + Water + Energy
CELLULAR RESPIRATION EQUATION: C 6 H 12 O 6 + O 2 CO 2 + H 2 O + Energy PHOTOSYNTHESIS EQUATION: CO 2 + H 2 O + LIGHT C 6 H 12 O 6 + O 2
3 Steps • There are three steps in the process of cellular respiration: – 1. Glycolysis – 2. Krebs Cycle (Citric Acid Cycle) – 3. Electron transport chain. • Get Krunk Everyone
• All 3 steps produce ATP. The electron transport chain produces the most!
Types of Cellular Respiration: Aerobic vs. Anaerobic • Aerobic- oxygen required • Anaerobic- no oxygen required – If oxygen is not present, products such as ethanol and CO 2 (single cell fungi (yeast) in beer/bread) or lactic acid (muscle cells) are produced. – Some organisms thrive in environments with little or no oxygen – Marshes, bogs, gut of animals, sewage treatment ponds

Where it takes place
Energy
Nutrient Absorption
Hormone Response • Phototropism
Gas Exchange • • Stoma- opening in the underside of a leaf that allows carbon dioxide and oxygen to diffuse into and out of the leaf Guard cell- specialized cell in the epidermis of plants that controls the opening and closing of stomata by responding to changes in water pressure
How it gets food • I can make my own food= A______. • I cannot make my own food=H____.
