BIO 120 TEST 2 QUESTIONS AND ANSWERS FULLY
EXPOUNDED!!
Which organelles are able to convert sun energy to chemical energy?
Nucleus
Ribosomes
Chloroplasts
Mitochondria


Answers :Chloroplasts are the site of photosynthesis becasuse they contain


Nuclei is the site of replication (DNA)
Ribosomes are the site of protein synthesis
Mitochondria is the site of respiration (ATP synthesis)
The pigment used for photosynthesis in eukaryotic cells is called?


Chlorine
Chloroplast
Chlorophyll
Chlorox
Chlorophorm


Answers :Chlorophyll


Chlorine is an element
Chloroplast is the organelle that contains chlorophyll

,Chlorox and Chlorophorm are jokes here
Which molecule is the waste gas in photosynthesis?


Methane (CH4)
Carbon Dioxide (CO2)
Hydrogen (H)
Oxygen (O)
Carbohydrate


Answers :O


CO2 is the waste of respiration
In which of the following is photosynthesis found?


1) animals, plants, protista, fungi, bacteria
2) plants only
3) all plants, some protista, and some bacteria
4) plants, protista, fungi, bacteria
5) only plants and bacteria


Answers :3) all plants, some protista, and some bacteria
Which of the following processes generates carbohydrates?


Glycolysis
Photosynthesis

,Fermentation
Aerobic Respiration
All of the above


Answers :Photosynthesis


Glycolysis breaks down glucose, producing ATP and pyruvate
Fermentation produces ATP without O
Aerobic Respiration produce ATP with O
At which step is carbon dioxide used in photosynthesis?


Light reactions
Calvin cycle
Respiration
Fermentaion
Glycolysis


Answers :Calvin Cycle (happens in the stroma; Uses ATP & NADPH to
incorporate CO2 into carbs; makes carbs; makes G3P)


Light reactions: happens in thylakoid membranes; produce ATP, NADH, O2;
elections adn H+ remain; O2 is exhaust (from H2O)


Respiration and Fermentation produces ATP and releases CO2 as waste
Glycolysis breaks down glucose to produce ATP and pyruvate
The O that is liberated in photosynthesis comes from?

, Carbon Dioxide
Sun
Water
Sugar
Air


Answers :Water


Photosynthesis uses CO2 and sunlight to produce sugar (glucose)
Cellular respiration = glucose + ____ --> carbon dioxide + water (C6H12O6 + ___
--> 6CO2 + 6H2O)


DNA
Oxygen
Chlorophyll
Sunlight


Answers :Oxygen (6O2)


Notably, this is the reverse of photosynthesis


DNA stores genetic code
Chlorophyll is the site of photosynthesis
Sunlight is a factor in photosynthesis
