Biology unit 1 test
What molecule would this be if it's high in nitrogen, soluble in water
Amino acid
Proteins are different based on number and type of ______ contains in their polypeptide chains
Amino acids
Proteins are important biomolecules that build organisms and direct chemical reactions. Proteins are polymers composed of long chains of
Amino acids
There are twenty different types of _____________ which join together in differing sequences and numbers to form different proteins.
Amino acids
This is a substance used to identify the presence of protein. It is a blue solution that changes to pink-purple in the presence of proteins.
Biuret solution
What is Starches and sugars Glucose and sucrose
Carbohydrate
Which biological polymer consists of many simple monosaccharides joined together?
Carbohydrates
Evolution
Change over time
The instructions for making proteins comes originally from
Chromosomes
This holds an organisms hereditary information.
DNA
What must something have to be considered living
Displays organization
DNA diversifies us into 3 major categories:
Domain archaea Domain bacteria Domain eukary
These are complex proteins that speed up chemical reactions by lowering the amount of energy needed to get the reaction started.
Enzymes
If you ate bacon and fried eggs for breakfast, the largest component of the energy would come from the
Fatsm
Mitochondria utilizes _____ as quick energy.
Glucose
One of the monosaccharides is a building block of a plant's cell wall. It is
Glucose
Monosaccharides are
Glucose fructose galactose and are for short term energy
Bio Logos
Greek, meaning life Greek, meaning study
A macromolecule made up of mainly carbon and hydrogen atoms that is primarily used for energy storage and in cell membranes.
Lipid
Can provide insulation Protein
Lipid
Which type of molecule makes up the double layer of a cell membrane?
Lipid
What forms the hydrophobic part of the plasma membrane and can be utilized for energy if sugars are not available
Lipids
What has a cell membrane a large bio molecule high energy bonds and includes waxes and steriods
Lipids
Which macromolecule contains steroids
Lipids
· cell membranes · large biomolecule · many high energy bonds · nonpolar covalent bonds · includes waxes and steroids · consists mainly of carbon and hydrogen · more energy per gram than other biomolecules The biomolecule described is a
Lipids
All living organisms display certain characteristics such as
Made of one or more cells Responds to stimuli Grows and develops Regulation (homeostasis) Requires energy Reproduces Evolve Displays organization
Carries genetic information
Nucleic Acid
This is a macromolecule that holds cell information in a coded form. Made of sugar, phosphate and nitrogen-containing bases.
Nucleic acid
What contains DNA AND RNA
Nucleic acod
___________ of glucose produces glycogen, the storage form of sugar, found in the liver and muscles.
Polymerization
A ___________ chain is a sequence of amino acids that is the foundation for the basic structure of a protein.
Polypeptide
In humans, excess blood glucose is stored in the liver and in muscle tissue in the form of glycogen. Glycogen is a long chain of glucose molecules bonded together. Because of this, glycogen is called a _____________________.
Polysaccharide
Cells are the functional unit of all life there are 2 categories:
Prokaryotic and eukaryotic Prokaryotic have been around lonher
Some are stringy and fibrous and provide support (i.e., collagen and keratin)Help speed up cellular reactions
Protein
A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair.
Proteins
DNA plays a major role in heredity, composing the genes that are passed down from parent to offspring. It also plays a major role in the everyday workings of your cells. It does this by creating molecules, such as enzymes, that regulate cell functions. These enzymes belong to a larger class of molecules known as
Proteins
What have antibodies to defend the cell against invaders
Proteins
Which molecule contains the most nitrogen
Protien
A single stranded nucleic acid that plays a role in protein synthesis.
RNA
This is a fat, most often of animal origin, that is solid at room temperature and whose fatty acid chains cannot incorporate additional hydrogen atoms.
Saturated
This is a lipid (fat) which contains one or more carbon-carbon double bonds and tends to be plant-based.
Unsaturated
Carbohydrate
Used as main source of energy for a cell
Animals store most of their excess energy reserves as _______ because
fat; they store twice as much energy per gram.
