Extended response 1. Write and label the correct balanced chemical equations for photosynthesis and
cellular respiration. Explain the relationship between these two equations. (6 points)
Cell Respiration: C6H12O6 + 6O2  6CO2 + 6 H2O + 38 ATP

Define consumer, producer, heterotroph, autotroph. Which perform photosynthesis? Which perform cellular
respiration?
-Consumers and heterotrophs both require energy from others. Gain energy by cell
respiration.
-Autotrophs and producers make sugars for energy/. They get there energy from
photosynthesis
-
Cellular respiration and Photosynthesis are examples of what kind of energy changes?
Cell resp- Takes glucose and converts it to ATP by changing chemical bonds
Photosynthesis- takes light energy and converts it to glucose.
-
Identify kinetic, chemical, potential, and electrical energy in a given scenario.
o Kinetic- motion; driving a car
o Chemical- energy in chemical bonds; bomb explosion
o Potential- position; bunger jumper on bridge
o Electrical- movement of electrons; battery
-
Compare and contrast combustion of a car with cell respiration in a cell.
o Similar- both require oxygen as reactant, both produce carbon dioxide and water, both give off heat
o Different- gas versus sugar for reactant
-
Calculate the amount of calories (grams of water X temperature change) and food Calories (calories/1000)
1 calorie = Temp. to raise 1g water 1 degree Celsius
100 mL= 100g X 10 degree Celsius = 1000gC
1000gC / 1000 = 1 kilocalorie or 1 Calorie (food calorie)
-
How is energy stored and released in ATP?
o Energy is stored in chemical bonds when ADP --> ATP
o Energy is released when chemical bods are made ADP--> ATP
o ADP has two phosphate, ATP has three phosphates

Explain how lactic acid and alcohol fermentation occur
o Alcohol fermentation creates ethyl (drinking) alcohol and carbon dioxide. Happens with yeast or bacteria.
o Both are anaerobic process - do not use oxygen.
-
How are foods made using fermentation? What kinds of foods are made?
o No oxygen, time creates flavor and carbon dioxide
o Cheese, yogurt, sauerkraut, alcoholic beverages
