The two major forms of calcium are calcium carbonate and calcium citrate. Calcium supplements are intended to be consumed with a meal, and when taken as directed, the two forms of calcium are absorbed at roughly the same rate. However, when taken on an empty stomach, the body has a much easier time absorbing calcium in its citrate form vs. its carbonate form. Calcium lactate and calcium stearate are two alternative forms of calcium. Calcium lactate is expected to have similar effects as calcium citrate.
PHYSICAL FACTORS THAT AFFECT MICROBIAL GROWTH. TEMPERATURE. Generally,an increase in temperature will increase enzyme activity. But if temperatures get too high, enzyme activity will diminish and the protein (the enzyme) will denature. On the other hand, lowering temperature will decrease enzyme activity. At freezing temperatures enzyme activity can stop. Repeated cycles of freezing and thawing can denature proteins.
B. Factors that Influence Bacterial Growth. Fundamental statements for this learning object: 1. Bacteria have a minimum, optimum, and maximum temperature for growth and can be divided into 3 groups based on their optimum growth temperature: psychrophils, mesophils, thermophils, or hyperthermophils..
