What is Cellular Respiration?

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

Energy Glucose+ Oxygen  Carbon Dioxide + Water + Energy The equation= Overall Reaction: C 6 H 12 O 6 + O 2 → CO 2 + H 2 O

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.lectron transport chain G et K runk E veryone G et K runk E veryone

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

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
