Let’s Review!! Respiration and Photosynthesis. What are the three products of aerobic respiration? Carbon Dioxide, Water and ATP energy.

1. Identify the raw materials of photosynthesis.

Chemical Pathways. Cellular Respiration Cellular respiration is the process that releases ___________ by breaking down glucose and other food molecules.

CELLULAR RESPIRATION. 1. Cellular Respiration – when cells break down simple food molecules such as glucose and release the energy they contain. A molecule.

Cellular Respiration In cellular respiration living things release the energy stored in food molecules. Cells may use aerobic respiration (using oxygen)

DN: Explain how plants regulate water loss

ENERGY AND CELLULAR RESPIRATION. Energy n Chemical energy – found in the bonds of food n Activation energy – energy needed to get a reaction started n.

Respiration Opposite Equation of Photosynthesis.  Opposite of Photosynthesis is respiration C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + Energy ATP Glucose.

Maintenance of Living Things

Photosynthesis Autotrophic Nutrition Light Energy Chemical Energy Equation:

Parts of the Leaf

Upper Epidermis / Cuticle Prevents water loss

Palisade Layer Photosynthesis Makes / Manufactures food (glucose)

Vein TRANSPORTS food and water Phloem: Food Xylem: Water

Stomate Gas Exchange

Guard Cell Controls the size of the opening

Cellular Respiration Used for ENERGY (ATP) Take place in the MITOCHONDRIA Used by Autotrophs and Heterotroph Equation:

Aerobic Respiration WITH Oxygen 36 ATP produced Mitochondria

Anaerobic Respiration WITHOUT Oxygen 2 ATP Produced Alcohol Fermentation (Yeast) Lactic Acid (Muscle Cramps) Cytoplasm

Transport Movement of Molecules

Passive Transport / Diffusion / Osmosis Movement from HIGH to LOW Does NOT use ATP (Energy) Osmosis: Diffusion of WATER from high to low High Low

Active Transport Movement from LOW to HIGH Uses ATP (Energy)
