Biochemistry Introduction

What is biochemistry?

-The study of chemical processes in organisms

-We will look at mostly organic molecules

Multiple Choice

What are organic molecules?

• Molecules based on oxygen

• Molecules based on carbon

• Molecules that are made in laboratories

• Molecules that organisms cannot make on their own

Multiple Choice

Is the molecule shown organic or inorganic?

• Organic

• Inorganic

Multiple Choice

What is unique about carbon and its bonding ability?

• It can bond with any element because it has 1 valence electron

• It can only bond with other carbon atoms

• It can form up to four different bonds because it has 4 valence electrons

• It can break down bonds in other molecules

Elements like to have a full valence (8 electrons), carbon has 4- so, it can form up to 4 different bonds to get 4 more electrons

Multiple Select

One type of organic molecule is a MACROMOLECULE. What are the 4 types of macromolecules? (SELECT ALL)

• Carbohydrates

• Lipids

• Proteins

• Sulfates

• Nucleic acids

Multiple Choice

Macromolecules are often POLYMERS. What are polymers?

• Really large molecules made from REPEATING smaller molecules

• Small building blocks

• Inorganic materials

• Large molecules made from oxygen

Macromolecules are often (but not ALWAYS) polymers

• Polymer= large molecule made from many smaller building blocks called monomers

Multiple Choice

What is the name of the reaction that builds polymers from monomers?

• hydrolysis

• acidification

• organic synthesis

• dehydration synthesis

Multiple Choice

What is the name of the reaction that breaks apart a polymer into monomers?

• dehydration synthesis

• condensation reaction

• hydrolysis

• acidification
