BIO 1500 FINAL EXAM HOMEWORK
ANSWERS STUDY GUIDE QUESTIONS
WITH CORRECT ANSWERS
Which of the following foods is likely to contain the most cellulose? - ANSWER-a
serving of broccoli
Phospholipids are important components of which cellular structure? - ANSWER-
membranes
What is the result of dehydration synthesis? - ANSWER-Two molecules form a
chemical bond with each other
Which of the following could be the outcome of hydrolysis? - ANSWER-A starch is
broken into simple sugar molecules
match the name of the process with how it happens. (note: reactant = a substance
that takes part in a chemical reaction) - ANSWER-dehydration synthesis: a water
molecule is removed from the reactant(s)
hydrolysis: a water molecule is added to the reactants
What type of organisms are responsible for the production of most of the oxygen on
Earth? - ANSWER-phytoplankton
What molecule is the source of the electrons in the electron transport chain? -
ANSWER-water
What molecule is the source of the oxygen that is released as a byproduct of
photosynthesis? - ANSWER-water
Which of the following is the same thing as a proton? - ANSWER-H+
What molecule is the source of the protons that are used to establish the proton
gradient? - ANSWER-water
What molecule does the electron end up in at the end of the two light reactions (i.e.
After Photosystems II and I)? - ANSWER-NADPH
What is the proton gradient used for? - ANSWER-making ATP
What does the term 'carbon fixation' refer to? - ANSWER-making organic
compounds
What is the difference (or relationship) between the terms diffusion and osmosis? -
ANSWER-they both function in the same way, but osmosis refers specifically to the
diffusion of water molecules
, Which of the following are the four categories of organic molecules? Note: the
question asks for the 4 categories, not for specific examples of organic molecules,
and not for the building blocks of organic molecules - ANSWER--carbohydrates
-lipids
-proteins
-nucleic acids
If a molecule is described as 'organic,' then which of the following statements must
be true? - ANSWER-it contains carbon
Which of the following are examples of carbohydrates? Choose 3 answers from the
list below. - ANSWER--glucose
-cellulose
-chitin
Which of the following are examples of lipids - ANSWER--olive oil
-bees wax
-bacon fat
When a fat is described as 'saturated,' what is it saturated with? - ANSWER-
hydrogen
Match the following organic molecules with their building blocks - ANSWER--
proteins: amino acids
- carbohydrates: simple sugars
- nucleic acids: nucleotides
- lipids: fatty acids
During the light-independent reactions, the Calvin Cycle requires NADPH and ATP.
Where does the cell get these molecules? - ANSWER-they are produced during the
light reactions of photosynthesis
The product of the light-independent reactions is a molecule called G3P. What does
the cell use it for? - ANSWER-building carbohydrates such as glucose
What is the overall function of photosynthesis, i.e. why do cells perform this process?
- ANSWER-to make carbohydrates like glucose
What are the two primary functions of all respiratory systems? - ANSWER--To
provide oxygen to the cells of the body
-To remove carbon dioxide from the body
All animals have a respiratory surface that gases cross. What is the mechanism by
which the gases move across the respiratory surface? - ANSWER-by diffusion
What is a limitation of this mechanism by which gases move across the respiratory
surface? - ANSWER-It's only efficient over small distances
