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
