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.
