This organic polymer is made up of small molecules called amino acids and functions to do work in cells.
What are proteins?
100
This type of fatty acid contains carbon atoms are bonded to as many hydrogen atoms as possible and tend to be solid at room temperature.
What are saturated fatty acids?
100
This class of organic compounds include substances such as fat or oil and are used as a long-term energy molecule as well as a water resistant membrane.
What is a lipid?
100
The millions of organic compounds can be grouped into these four major types of compounds.
What are carbohydrates, lipids, proteins, and nucleic acids?
100
This type of fatty acids contain carbon atoms not bonded to as many hydrogen atoms as possible and tend to be liquid at room temperature.
What are unsaturated fatty acids?
200
reactions in organisms are called this as these reactions break down molecules into smaller units and release energy.
exothermic
200
Water is known to have a difference in electrical charge between different parts of the same molecule, this water is this type of molecule.
What is a polar molecule?
200
This is a process that changes some chemical substances into others.
What is a chemical reaction?
200
A chemical reaction that absorbs energy is called this.
What is an endothermic reaction?
200
Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the this.
What is the active site?
300
This class of organic compounds include sugars or starches, and are used to store energy.
What are carbohydrates?
300
Acidity is measured on this scale.
What is the pH scale?
300
A solution with a pH lower than 7 is called this.
What is an acid?
300
The concentration of hydronium ions in a solution is known as this.
What is acidity?
300
The type of bond that forms between polar molecules like water is known as this.
What is a hydrogen bond?
400
A substance that is an input to a chemical reaction is called a this, and a substance that forms as a result of a chemical reaction is called this.
What are reactants and products (respectively)?
400
These are proteins that speed up chemical reactions in cells in temperatures that are far below that of burning flesh.
What are enzymes?
400
A solution with a pH higher than 7 is called this.
What is a base?
400
This class of organic polymers include molecules such as DNA or RNA, are built of small units called nucleotides, and serve as information molecules.
What are nucleic acids?
400
This organic polymer is a complex carbohydrate that forms when simple sugars bind together in a chain and serve as energy and structural molecules.
What are polysaccharides?
500
reactions in releases less energy than it takes in
Endothermic
500
The sum of all the biochemical reactions in an organism is called this.
What is metabolism?
500
This is a process that changes some chemical substances into others.
What is a chemical reaction?
500
The energy needed to start a chemical reaction is called this.
What is activation energy?
500
A chemical reaction that releases energy (as heat) is called this.
