Chapter 25 & 2 Flashcards
How many atoms can make up an organic compound? These types are called?
thousands / macromolecules
Macromolecules are composed of?
small building blocks
Name the 4 main groups of organic compounds
Carbohydrates, lipids, proteins, nucleic acids
What are the best examples of carbohydrates?
sugars and starches
Carbohydrates function in providing this for cells?
short - term, quick energy
Carbohydrates contain what elements? (3)
Carbon, hydrogen, oxygen
Name the 3 classifications of carbohydrates
monosaccharides, disaccharides, polysaccharides,
these are simple sugars
monosaccharides (simple, mono, one)
examples of monosaccharides
glucose and fructose
During digestion, carbohydrates are broken down into what form? Why? They are used for?
monosaccharides which is small enough to get into cells and be used for fuel
these are complex sugars consisting of 2 monosaccharies covalently bonded to one another
disaccharides
examples of disaccharides
sucrose and lactose
table sugar
sucrose
milk sugar
lactose
These are complex carbs consisting of many simple sugars covalently bonded to one another to form a long chain.
polysaccharides
examples of polysaccharides
starch and glycogen
What is the storage form of glucose in plants?
starch
This is the storage form of glucose in animals (within liver and muscle cells)
glycogen
examples of lipids
fats and oils
lipids function in providing this for cells
long-term fuel
this makes up the cell membranes of cells?
lipids
are lipids soluble in water?
no
lipids contain what 3 elements?
carbon, hydogen, oxygen
lipids are partially composed of?
fatty acids
3 classifications of lipids
Monoglycerides, diglycerides, triglyceries
how many fatty acids does monoglycerides contains? diglycerides? triglyceries?
1, 2, 3 respectively
proteins have what kind of functions?
various
What 5 elements do proteins contain?
carbon, hydrogen, oxygen, nitrogen, sulfur
Proteins are composed of these which are covalently bonded to one another to form a long chain
amino acids
Name a few examples of proteins (6)
enzymes, hemoglobin, collagen, antibodies, actin, and myosin
what chemicals help to speed up chemical reactions in living things.
enzymes
this is a long chain of amino acids
polypeptide
these consist of several polypeptide chains.
globular proteins
What can be done to proteins during extreme condidtions such as heat or acidity.
Denatured
When proteins are denature, what changes causing what to happen?
its shape and it can no longer carry out its function.
Name 2 examples of Nucleic Acids
DNA & RNA
What elements are contains in DNA and RNA? (5)
carbon, hydrogen, oxygen, nitrogen, and phosphorus
DNA makes up?
genes
these are the basic units of inheritance
genes
RNA is involved in?
protein synthesis by cells.
