Biology Unit 7 Flashcards

Front

active site

Back

the region on the substrate where an enzyme binds

Front

adenine

Back

one of the four nitrogen bases that combine with sugar and phosphate to form a nucleotide subunit of DNA; adenine pairs with thymine in DNA and pairs with uracil in RNA

Front

amino acid

Back

monomer proteins

Front

ATP

Back

(adenosine triphosphate) Biochemical molecule that contains chemical energy stored in its high-energy phosphate bonds. It releases energy when phosphate bonds break creating ADP. Produced during cell respiration

Front

biochemical

Back

chemicals and their reactions that make life possible and determine the characteristics of living things

Front

catalyst

Back

substance that speeds up the rate of a chemical reaction without being changed or used up by the reaction

Front

chemical reaction

Back

two or more substances chemically combining to produce a new substance

Front

chromosomes

Back

thread-like structures in the nucleus that are made up of DNA and protein; humans have 23 pairs of chromosomes

Front

codon

Back

a three nucleotide sequence of mRNA that is complementary to a tRNA anticodon

Front
