Introduction to Anatomy Unit Vocabulary

Cell

• Toward or at the back of the body; behind
• The monomer of proteins
• The most basic structural and functional unit of life; the smallest part of an organism that is still capable of all life's processes
• Toward or at the body surface

Organelle

• Toward or at the front of the body; in front of
• Molecules that speed up biochemical reactions by lowering the activation energy needed to get the reaction going without changing the reactants or products
• A sagittal plane that crosses through the midline of the body
• Specialized structures within the cell that work together to help the cell function

Macromolecule

• The monomer of nucleic acids
• One or more cells that create and secrete different products
• Biological catalysts; mostly proteins
• Key large biological molecules that make up all living things

Nucleotide

• Addition of a phosphate group by kinases that changes a molecule's shape and contributes to transduction
• The monomer of nucleic acids
• The most basic structural and functional unit of life; the smallest part of an organism that is still capable of all life's processes
• Away from the upper part; toward the lower part; below

Fatty Acid

• The monomer of lipids
• An action that evokes a response
• Horizontal plane that divides the body into superior and inferior sections (above and below)
• Highly specialized nerve cells that make up nervous tissue and generate and conduct nerve impulses

Monosaccharide

• The monomer of carbohydrates
• The monomer of nucleic acids
• Toward or at the midline of the body; on the inner side of
• The study of cells

Amino Acid

• The study of tissues
• Addition of a phosphate group by kinases that changes a molecule's shape and contributes to transduction
• Flat surfaces used to divide the body into different sections
• The monomer of proteins

Enzyme

• internally secreting (Ex. Hormones as products)
• Type of serous membrane that lines the body cavity
• The highly specific location on an enzyme where substrates (reactants) bind
• Biological catalysts; mostly proteins

Catalyst

• An organ that does the response
• The study of cells
• Molecules that speed up biochemical reactions by lowering the activation energy needed to get the reaction going without changing the reactants or products
• A small molecule that serves as an intermediate between the receptor and the cascade of responses after

Active Site

• The highly specific location on an enzyme where substrates (reactants) bind
• A sagittal plane that crosses through the midline of the body
• internally secreting (Ex. Hormones as products)
• Addition of a phosphate group by kinases that changes a molecule's shape and contributes to transduction
