Life Science 3C

life and cells - molecules & life (biochemistry)

What do all things in the room have in common matter and energy
what is matter anything that has mass and takes up space
what is energy anything that brings about change (can hold matter together or break it apart)
What is food you eat matter held together by chemical energy
when something is made up of only one kind of atom it is an element
the smaller structures inside a cell are molecules
what are atoms the smallest unit of an element
what makes up a molecule atoms
a group of atoms held together by the energy of chemical bonds molecule
what are the 4 categories of molecules that are essential to life Carbohydrates, Proteins, Nucleic Acids, Lipids
is made up of CHO and supplies energy for cell processes and some are important parts of cell structures carbohydrates
examples of carbohydrates glucose, cellulose,starch,glycogen,sugar
what are proteins building blocks of many structures in organisms and are involved in almost everything that happens in a living cell
What are proteins made up of amino acids
What is an enzyme a protein that regulates nearly all chemical reactions in a cell
Nucleic Acids are made up of Nucleotides
DNA (nucleic acid) carries info that directs each cells activities
RNA (nucleic acid) needed to make enzymes and other proteins
