Review What is the difference between atoms and elements?
Elements are made of one kind of atom; an atom is the smallest amount of an element What is the difference between atoms and molecules? Molecules are atoms bonded together

What is a macromolecule?
A macromolecule is a large molecule made up of smaller organic (naturally- occurring) molecules. There are 4 basic kinds: Carbohydrates Lipids Proteins Nucleic Acids C, H, O C, H, O, and P C, H, O, N, S C, H, O, N, P

What is a macromolecule?
A macromolecule is a large molecule made up of smaller organic (naturally- occurring) molecules. For carbohydrates, proteins, and nucleic acids the smaller molecules are called monomers. When the monomers join together, they are called polymers. POLYMER Monomer Monomer Monomer Monomer Monomer Monomer
8
What is a carbohydrate? Carbohydrates are the body’s “Fast Fuels”
very little energy is required for the body to break them down and release their energy They are the sugars that we love so much Made up of C, H, O in a 1:2:1 ratio Most simple is a monosaccharide (glucose) Two become a disaccharide More than that it becomes a polysaccharide

What is a carbohydrate? Complex Really Complex! Simple
11
What is a lipid? Lipids are the body’s “long term” storage for energy.
It takes energy to break down lipids, but they release much more than carbohydrates. The body will first use “quick fuel” in carbohydrates then turn to lipids as fuel.

13
What is a lipid? Lipids are the fatty foods that we love to eat and are made in our body from excess calorie intake. They also make up our cell membrane. Made up of C, H, O (and P in cell membrane) There are many different kinds of lipids Fats – oils, animal fat, etc Phospholipids – cell membrane material Waxes - waterproof coatings on leaves, fruit, feathers, etc. Steriods - cholesterol, hormones, bile, etc.

What is a lipid? Fats Steroids Waxes
16
What is a protein? Proteins are the most complex and diverse macromolecules in living organisms. Make enzymes, blood cells, muscle tissues, and much more Made of C, H, O, N, and S Created by DNA and RNA coding (we’ll discuss this later)
17
What is a protein? Like carbohydrates, proteins are polymers.
Proteins are made from individual monomers called amino acids. Amino acids join together in long polymer chains called peptide chains. Interactions between parts of these chains mold them into different shapes. Amino Acid Amino Acid Amino Acid Amino Acid Amino Acid Amino Acid
19
What is a protein? Keratin Plant Protein (hair) Keratin (fingernails)
Muscle
20
What is a nucleic acid? Nucleic acids are the macromolecules found in all cells that provide the genetic code for that organism. There are two main kinds of nucleic acids.
21
Deoxyribonucleic acid (DNA)
22
Ribonucleic acid (RNA)
23
What is a nucleic acid? Nucleic acids are the macromolecules found in all cells that provide the genetic code for that organism. There are two main kinds of nucleic acids. Deoxyribonucleic acid (DNA) Ribonucleic acid (RNA) Made of C, H, O, N and P.
24
Two Nucleic Acids
25
What is a nucleic acid? Nucleic acids are also polymers because they are made of smaller molecules The monomers of nucleic acids are called nucleotides Each nucleotide is made of phosphate group 5 carbon sugar Nitrogenous base P Base S P Base S P Base S
26
What is a nucleic acid? The monomers of nucleic acids are called nucleotides Made of a phosphate group, sugar, base 5 kinds of nitrogenous bases Guanine Cytosine Adenine Thymine (only in DNA) Uracil (only in RNA)

Water Properties Lab
51
Molecular Structure The uniqueness of water comes from its:
The polarity of water is responsible for effectively dissolving other polar molecules, such as sugars and salts. Because water is able to dissolve so many common substances, it is known as the universal solvent. Why do our cells need to be able to dissolve other molecules? Why should water be cohesive within the cell? Ease of movement through biological membranes.
52
Water Properties Lab
53
Water molecules tend to stick to each other in a regular pattern, called cohesion.
Water molecules tend to stick to other molecules. This is called adhesion.
54
A type of cohesion is surface tension.
This occurs when water molecules align to create a “net” made of atoms.
55
Water Properties Lab
56
Surface tension keeps cells functional.
It ensures the proper organization of their biomolecules, proteins, lipids, and nucleic acids, into membranes and various types of cellular organelles.
58
Capillary action is when adhesion to the walls is stronger than the cohesive forces between the liquid molecules, causing an upward force.
60
These water properties are not independent of each other
These water properties are not independent of each other. Polarity causes surface tension, a product of cohesion and adhesion, which causes capillary action . . .
61
Compared with other molecules, water can absorb or release large amounts of heat while adjusting its own temperature a small amount. A large part of all living things is made of water. Helps the body maintain optimum temperature ranges.
62
Sweating – capillary action, heat capacity, homeostasis
Sweating – capillary action, heat capacity, homeostasis. Wilting – loss of water, turgidity decreases (cohesion, capillary action, adhesion)
