Amino acids - ANSWER-20 different types, joined by peptide bonds to make proteins
, Nucleic Acids - ANSWER-function in energy transport (ATP), hereditary material (DNA),
and protein synthesis (RNA)
Nucleotides - ANSWER-Adenine, Thymine, Guanine, and Cytosine
Anabolism - ANSWER-enzymes that make molecules
Catabolism - ANSWER-enzymes that break molecules
Transcription - ANSWER-make a working copy of the gene
Translation - ANSWER-translate the nucleotides to amino acids
Cytoplasm - ANSWER-fluid inside the cell
Nucleus - ANSWER-location of DNA, production from RNA
Endoplasmic Reticulum - ANSWER-location of translation (protein synthesis)
Golgi Bodies - ANSWER-stacks of membranes, packages proteins for transport in
membrane bubbles called vesicles
Mitochondria - ANSWER-production of ATP
Cytoskeleton - ANSWER-network of proteins in the cytoplasm, function: structural
support, tracks for transport of vesicles and organelles
Plasma Membrane - ANSWER-made of phospholipids and cholesterol, is selectively
permeable
