Question Answer
ADH ( Antidiuretic hormone) The hormone made in the hypothalamus and released from the pituitary gland that acts on the collecting ducts in the kidneys to increase the reabsorption of water into the blood.
Ascending Limb The limb of the Loop of Henle that carries fluid from the medulla towards the cortex of the kidney.
ATP (Adenosine Triphosphate) Molecule (nucleotide derivative) found in all living cells and involved in energy transfer. When it is hydrolysed energy is released.
ATP synthase Enzyme associated with stalked particles in mitochondria and chloroplasts. It catalyses the joining of ADP and inorganic phosphate to make ATP.
Basement membrane A layer of connective tissue- mostly collagen-that holds an epithelium in place.
Bilirubin One of the waste products from breaking down hemoglobin.
Bowman's capsule The cup-shaped end of the nephron tubule.
Co-transporter proteins Proteins in the cell surface membrane that allow the facilitated diffusion of simple ions to be accompanied by transport of a larger molecule such as glucose.
Deamination The removal of the amine group from an amino acid to produce ammonia.
Descending Limb The limb of the Loop of Henle that carries fluid from the cortex towards the medulla of the kidney.
Detoxification Conversion of toxic substances, such as alcohol, to less toxic substances.
Distal Convoluted tubule The coiled portion of the nephron between the loop of Henle and the collecting duct.
Efferent Outgoing or leading away from.
Endothelium The tissue which lines the inside of a blood vessel or nephron.
Epithelium The tissue that covers the outside of a structure.
