Visualizing Photosynthesis and Cellular Respiration- LETS MAP IT OUT!

Background Information:

Photosynthesis

Photosynthesis is one of the most important biological events that occur on this planet. It is defined as the process by which plants use solar energy (absorbed by the chlorophyll in the chloroplasts of leaves) to convert raw materials into food. The raw materials are carbon dioxide, which diffuses through small holes in the underside of the leaves called stomata, and water. The food creates is the sugar monomer glucose. As a by-product of photosynthesis oxygen gas is also produced. The general chemical equation for photosynthesis is

Chemical Symbols:

6H2O + 6 CO2 + solar energy ------ C6H12O6 + 6 O2

Molecular Structures:

+ C=O=C + SUN ------> + O=O

LIGHT

Cellular Respiration

Simply stated, respiration is the release of energy in the form of ATP from the energy-storing compound glucose. Essentially it is the reverse of photosynthesis, which the only difference being the form energy takes in the equation. It is represented by the chemical equation:

Chemical Symbols:

C6H12O6 + 6 O2 ------> 6 CO2 + 6 H2O + 36 ATP

Molecular Structures:

+ O=O ------> C=O=C + +

Directions

1. Using colored pencils/crayons color or circle the chemicals in all four equations above. Use the following colors for each molecule(s)…

Water  Blue

Carbon Dioxide  Red

Glucose  Green

Oxygen  Orange

Sunlight/ ATP (Energy) Yellow

YOUR TASK:

You and a partner will work to create two drawings. One of the Mitochondria and one of the Chloroplast. You can work together on both or divide and conquer each completing one. Use your textbook to reference a drawing that includes the vocab below and identify the key components of each and explain what happens as energy is absorbed or converted.

Autotroph

Heterotroph

Aerobic respiration

lactic acid fermentation

ADP

Electron Transport Chain:you do not need to know the individual steps just reactants and products

light-dependent reaction

Alcoholic fermentation

Krebs Cycle (Citric Acid Cycle): you do not need to know the individual steps just reactants and products

light-independent reaction

Anaerobic respiration

NAD

ATP

NADH

Chlorophyll

Thykaloid

Chloroplast

Stroma

Glycolysis:you do not need to know the individual steps just reactants and products

Calvin Cycle

Glucose

Grana

Drawings will be graded on inclusion of appropriate vocabulary with definitions and not artistic ability but the drawings should look like you took your time!

Post Drawing: Questions: Each person should do these questions individually! Attach these questions and the first page with the colors to your drawings with a paperclip to get full credit.
