Carbohydrates and proteins are two types of macromolecules. Which functional characteristic of proteins distinguishes them from carbohydrates?
Ability to catalyze chemical reactions
Bases of DNA
Adenine, Thymine, Guanine, Cytosine
Amino Acid Structure
Alpha Carbon Amino Group R Group Carboxyl Group
Glycogen and starch
Are carbohydrates in which energy is stored
All organic compounds contain
Carbon
What is the backbone of all organic molecules
Carbon
lipids are Made from links of
Carbon and Hydrogen
What are examples of nucleic acids
DNA, RNA, ATP
What are lipids functions
Fats: Storage of energy Phospholipids: Found in cell membranes. Helps contain the parts of the cell. Helps regulate the
Glycogen
Linked glucose Found in animal cells Storage form of energy
Starch
Linked glucose Found in plant cells Storage form of energy
What are the building blocks of Lipids
None
Nucleotide Structure is a
Phosphate and sugar base
What are carbohydrates functions
Provide and store energy.
What are Proteins functions
Speed up chemical reactions, Structural Functions,Help immune response, Muscle contraction
Cellulose
Structural protein Found in plant cells Cannot be digested
What are Nucleic acids functions
Template for production of proteins(RNA),Contains hereditary information(DNA), Energy for cellular reactions(ATP)
The bases of RNA are...
adenine, cytosine, guanine, uracil
What are the building blocks of proteins?
amino acids
Satured fats are found in
animals
Found in cell membranes as a lipid
bilayer
DNA has the sugar _____ while RNA has the sugar ribose
deoxyribose
What are examples of proteins
enzymes and antibodies
What are examples of lipids?
fats, steroids, phospholipids, waxes
unsatured fats are ________ at room temp
liquid
Formed from ___________ of amino acids that are linked together
monomers
What are the building blocks of Carbohydrates
monosaccharides
Fat molecules typically contain long chains of carbon atoms. Animals tend to store fats for use when food resources are scarce. This is an advantage to the animal because
much energy can be gained by breaking the bonds between atoms in the fats
Are lipids nonpolar or polar molecules?
nonpolar
Are lipids soluble or nonsoluble in water
nonsoluble
What are the building blocks of Nucleic acids
nucleotides
unsatured fats are found in
plants
reactants make
products
satured fats are ________ at room temp
solid
What are examples of carbohydrates?
starch, glycogen, cellulose
