Active absorption requires input of energy, which is obtained from cellular respiration. Respiration is an enzymatic process and is inhibited at extreme temperatures. Hence, the optimum temperature for active absorption is twenty to thirty five degree celsius.

Taq DNA polymerase is the most common enzyme used for PCR amplification. This enzyme is extremely heat resistant with a half-life of 40 minutes at 95°C. At its optimal temperature (72°C), nucleotides are incorporated at a rate of 2–4 kilobases per minute.

Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, ( 4.4°C- 60°C) doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone." To learn more about the "Danger Zone" visit the Food Safety and Inspection Service fact sheet titled Danger Zone.

The optimum temperature range for yeast fermentation is between 90˚F-95˚F (32˚C-35˚C). Every degree above this range depresses fermentation. While elevated temperature is problematic in all phases of ethanol production, it is specifically hazardous during the later stages of fermentation.

High Temperatures Weak interactions between amino acids on different parts of the chain are what give the protein / enzyme its shape. If the temperature is increased too greatly, this will disrupt these weak bonds and cause the protein to denature (change shape) and the substrate won't fit into the active site.

Factors affecting enzyme activity Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

Now that enzymes are available that are stable above 100 degrees C it is possible to investigate conformational stability at this temperature, and also the effect of high-temperature degradative reactions in functioning enzymes and the inter-relationship between degradation and denaturation.

Enzymes need to be stored and used at their optimum temperatures. Enzymes are generally stored in glycerol at -20C. This prevents them from freezing completely, which causes protein denaturation and results in a loss of activity.

An enzyme is a protein that catalyzes (increases the rate of) chemical reactions. The optimal temperature of most enzymes, or the temperature at which enzymes best facilitate reactions, is between 35 and 40 degrees Celsius.

Given that complement activation is severely inhibited at near 0°C temperatures, we then evaluated complement activation for temperatures ranging from 0°C-37°C. Antibody-initiated complement activation in human serum increased as temperature decreased from 37°C to 24°C until dramatically decreasing at 13°C (Figure 1B).

The organisms grew well in Trypticase soy broth (BBL Microbiology Systems) between 30 and 42 degrees C, with 37 degrees C being optimal for growth. E. coli O157:H7 grew poorly in the temperature range (44 to 45.5 degrees C) generally used for recovery of E. coli from foods.

The optimum temperature for human lactase is about 37 °C and the optimum pH is 6. In metabolism, the β-glycosidic bond in D-lactose is hydrolyzed to form D-galactose and D-glucose, which can be absorbed through the intestinal walls and into the bloodstream.
