define buffering - protein molecules aid in resisting extreme pH shifts in food products define canning - food is heated after packed in can define carmallization - Application of heat to a carbohydrate (physical browning) define curing - high concentrations of salt added to foods for the purpose of preservation define fermentation - Growth of bacteria and/or yeast under conditions of limited to no available oxygen. MOs consume energy source and produce ethanol and carbon dioxide! • Ferm...

Anterior interventricular sulcus - A branch of the left coronary artery that supplies muscles of each ventricle. Aorta - THE MAIN ARTERY, WHICH RECEIVES BLOOD FROM THE LEFT VENTRICLE AND DELIVERS IT TO ALL THE OTHER ARTERIES THAT CARRY BLOOD TO THE TISSUES OF THE BODY. Aortic valve - Heart valve between the left ventricle and the aorta. Opens to allow blood to leave the heart. Artery - A blood vessel that carries blood away from the heart. Basophils - *Release histamines, heparin and othe...

Which of the following phenomenon is a result of starch retrogradation? - Bread tends to stale rapidly in a refrigerator and becomes dry 2 types of fermen...

blocking buffers - Used to prevent nonspecific binding interactions between the antibodies and nitrocellulose membrane. Added after transfer to nitrocellulose before antibody staining. 10X TBST: designed for washing the blots in between stains and 5%nonfat dried milk. bromophenol blue - ph marker. used to indicated when the protein reached the bottom of the electrophoresis Coomassie Blue - a dye that stains proteins blue and allows them to be visualized. it binds to arg, lys, his residues ...

_____ law states that the volume of a gas is inversely proportional to its pressure. - Boyle's A common condition characterized by acute inflammation of the tracheobronchial tree is - acute bronchitis. Correct A right shift of the oxygen-hemoglobin dissociation curve due to increased partial pressure of carbon dioxide is also known as - the Bohr effect. Correct According to the law of partial pressures, the partial pressure of gas in a mixture of gases is - directly related to the concent...
