What are the four classes of macromaolecules? - Answer✔Carbohydrates, lipids, proteins, &
nucleic acids
If a molecule is described as 'organic,' then what must be true? - Answer✔It contains carbon
What are three examples of carbohydrates? - Answer✔Glucose, chitin, & cellulose
What are three examples of lipids? - Answer✔Oil, wax, & fat
When a fat is "saturated", what is it saturated with? - Answer✔Hydrogen
What is the building block of proteins? - Answer✔amino acids
What is the building block of lipids? - Answer✔fatty acids
What is the building block of carbohydrates? - Answer✔simple sugar
What is the building block of nucleic acids? - Answer✔nucleotides
What are the characteristics of saturated fats? - Answer✔-solid at room temperature
-have single bonds within the carbon chain
-usually obtained from animal sources
-do not dissolve in water easily
Where is cellulose mostly found? - Answer✔Cell walls of plants (leafy vegetables)
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
What is dehydration synthesis? - Answer✔Dehydration synthesis is when you remove one H2O
molecule to combine two reactants (creates polymers)

What is the result of hydrolysis? - Answer✔The molecule is split into two products (ex starch
broken into simple sugars)
What is hydrolysis? - Answer✔Hydrolysis is the separation of two reactants by adding H2O
molecule (creates monomers)
Biological macromolecules are ________, that are constructed from ________ . -
Answer✔polymers, monomers
Why do cells perform cellular respiration? - Answer✔to create ATP
What are the inputs of cellular respiration? - Answer✔oxygen & glucose
What are the three steps of cellular respiration? - Answer✔1. Glycolysis
2. Pyruvate Prep/Citric Acid
3. Electron Transport Chain
What is glycolysis? - Answer✔The breaking down of glucose to release 2 net ATP & 2 NADH
What is the pyruvate prep/citric acid cycle? - Answer✔Pyruvate is oxygenated & broken down
in a series of chemical reactions, regenerating more NADH/FADH2 (electron carriers), & CO2 as
a byproduct
What is the electron transport chain? - Answer✔The sequence of electron carrier molecules
that shuttle electrons down a series of redox reactions that release energy and create a proton
gradient; H2O is produced as a byproduct, with this H+ re-entering the mitochondrial matrix
through ATP synthase, resulting in ATP.
What is the primary output of CR, and what are the by-products? - Answer✔ATP is the primary
output, CO2 & H2O are the byproducts
Why do people die if their supply of oxygen is cut off? - Answer✔Oxygen acts as the final
electron receptor, meaning that without oxygen available, this process entirely stops, and the
protons are no longer able to be transported to the inter membrane space and stored as
potential energy.
Trace the flow of energy through CR. (Where does it begin? Where is it at the end of the citric
acid cycle? Where is it at the end of the electron transport chain?) - Answer✔It begins in bonds
of glucose, then becomes NADH/FADG2 (end of glycolysis), then H+ concentration gradient
(end of pyruvate prep/citric), and then finally becomes stored ATP (end of ETC).
In what way do cells use glucose during the production of ATP? - Answer✔Cells transfer some
of the energy stored in glucose's chemical bonds to ATP.
During the electron transport chain, protons are pumped across the inner membrane, from the
matrix to the Inter-membrane space. What is the function of this step? - Answer✔The function
