Photosynthesis

Chemical Reactions CHEMICAL REACTION ___________________________ - breaking bonds between atoms and forming new ones to make new compounds Reactant - ______________________________________ Product - ______________________________________  In the equation below, label the reactants and products: C6H12O6 + 6O2 6CO2 + 6H2O + ATP ________________ ________________ CHEMICAL REACTION GOES INTO THE REACTION (INGREDIENTS) WHAT’S MADE PRODUCTS REACTANTS Photosynthesis

Photosynthesis Definition – Equation – (carbon dioxide) (water) (glucose) (oxygen) CONVERTING SUN’S ENERGY INTO FOOD ENERGY (GLUCOSE) CO2 + H20 + LIGHT C6H12O6 + O2 Photosynthesis

Chloroplast Structure: 3. Location - Chloroplast Structure:   CHLOROPLAST How do plants absorb light? Notice the stacks inside of the chloroplast. These stacks absorb sunlight. This arrangement increases the amount of __________________________________ to absorb as much sunlight as possible. SURFACE AREA

Pigments PIGMENTS ABSORB REFLECT REFLECTS GREEN PHOTOSYNTHESIS Plants contain _____________________ that _______________ some wavelengths of light and ________________ others. ABSORB REFLECT For example, if a plant appears red, the plant ________________ this color. ______________________ is one of the most abundant pigments in a plant which absorbs the red and blue colors of the spectrum and reflects ________________ which is what makes plants appear green. The light plants absorb is used to undergo __________________________. REFLECTS CHLOROPHYLL GREEN PHOTOSYNTHESIS

Cellular Respiration

Cellular Respiration Definition – Analogy: glucose is like a , ATP is like the process of converting chemical energy (glucose) into useable energy (ATP) check cash Cellular Respiration Animation

Location: Notice the highly folded inner membrane. These folds increase the amount of so lots of ATP can be made. MITOCHONDRIA SURFACE AREA

The equation for aerobic respiration is: Occurs with ___________________ The equation for aerobic respiration is: _________ + _________  ________ + _______ + ___ATP OXYGEN C6H12O6 O2 CO2 H20 36 GLUCOSE OXYGEN CARBON WATER DIOXIDE

Anaerobic Respiration Occurs without . Two types of fermentation 1. ALCOHOLIC Fermentation occurs in _____________. Equation: __________ ________ + _____ + ____ ATP This process is used in baking bread and in brewing. What causes bread dough to rise? _____________ (FERMENTATION) OXYGEN Yeast C6H1206 ETHANOL CO2 2 CARBON DIOXIDE Cheeseburger Chemistry

Lactic Acid Fermentation - occurs in cells Equation: ______________ __________________ + _____ ATP This process occurs when exercising. If your muscles are depleted of oxygen they will switch to lactic acid fermenation. Lactic acid builds up in the muscles and creates that ___________________ feeling.   What reactant is missing from both of the equations above? ___________ MUSCLE C6H12O6 LACTIC ACID 2 BURNING OXYGEN Respiration Song

Structure of ATP & ADP:   Energy is stored in the bonds between the , when the bonds break energy is to power chemical reactions, your cells and ultimately your body. The goal of cellular respiration is to take ADP and create ATP by adding on a _______________. Sugar PHOSPHATES RELEASED PHOSPHATE
