Photosynthesis & Cellular Respiration
Name:_______________________________________________
Vocabulary: Match the phrases on the left with the term that best fits. Use answers only one time.
J 1. Organisms that make their own food A. Chloroplasts
A 2. Site of photosynthesis B. Aneorobic
F 3. Process occurs in a mitochondrion C. Aerobic
D 4. C 6 H 12 O 6 D. Glucose
B 5. Process does not require oxygen E. ATP
C 6. Process requires oxygen F. Kreb’s cycle
I 7. Adenosine diphosphate G. Glycolysis
E 8. Energy storing molecule H. Energy
G 9. The anaerobic process of splitting glucose I. ADP and forming two molecules of pyruvic acid J. Autotrophs H 10. The ability to do work
Directions: Answer each of the following questions in a clear and concise manner.
- Compare and discuss how cells store energy and release energy using ATP. Be specific! You may draw the cycle. ATP loses a phosphate bond to release energy (ADP) and gains a phosphate bond to gain energy (ATP)
- Compare lactic acid fermentation and alcoholic fermentation by describing what pyruvic acid is changed into. Be sure to include what type of organism each one takes place in.
What is pyruvic acid changed into? (^) Organism:
Alcoholic Fermentation ETHYL ALCOHOL
BATERIA, YEAST
Lactic Acid Fermentation LACTIC ACID
MUSCLE CELLS, SOME BACTERIA
(LACTOBACILLUS IN YOGURT)
- Name the three processes of aerobic cellular respiration. How many ATP’s does each process produce, and what is the total ATP produced from one glucose?
3 Processes of Cellular Respiration: # ATP produced:
GLYCOLYSIS
KREBS CYCLE 2
ELECTRON TRANSPORT CHAIN
(ETC)
- Name the two stages of photosynthesis and list the starting molecule(s) and ending molecule(s) of each.
Stages Starting Molecule(s) Product(s)
LIGHT-DEPENDENT REACTION
WATER OXYGEN
LIGHT-INDEPENDENT
REACTION OR DARK
CYCLE OR CALVIN CYCLE
CARBON DIOXIDE GLUCOSE
- What is the general chemical equation of photosynthesis?
CARBON DIOXIDE + WATER OXYGEN + GLUCOSE CO2 + H2O O2 + C6H12O
- a. Cellular respiration can be either AEROBIC ("with oxygen") or ANAEROBIC ("without oxygen").
b. Anaerobic respiration occurs in the CYTOPLASM of cells whereas aerobic respiration occurs in the MITOCHONDRIA of cells.
Total ATP per 1 glucose = 36
