Enzymes are proteins, and proteins are designed to exist at specific temperatures and pH levels. When the temperature or the pH of their environment changes, the interactions that hold the amino acids of the enzyme in its particular conformation cease to function. The protein simply "falls apart" into an unstructured assembly of amino acids (a polypeptide still, but no longer a true protein) and cannot fulfill its function; this is called denaturation. For most enzymes, this occurs with an increase in temperature or a decrease in pH from their standard physiological environment.

What are 3 things that can alter enzyme activity?
1. Temperature. 2. P.H level. 3. Enzyme concentration
What are two factors that influence enzyme activity?
Concentration of the enzyme or it's substrate and the temperature.
What are the four factors that effect enzyme activity?
temperature, pH, concentration of enzymes, and concentration of substrates.
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
How might amino acid change affect the enzyme?
The pKA of enzyme affects its ionization which could alter enzyme activity. For pH < pKa, the value of vmax is constant and that for pH > pKa, vmax decreases; ie. enzyme activity starts to decline.

Temperature and can affect enzyme activity?
Ph level, enzyme concentration, substrate concentration etc
What are factors affecting enzyme activity?
Concentration ( enzyme to substrate ), temperature and pH.

temperature, pH, concentration of enzymes, and concentration of substrates.

What may affect enzyme activity?
Temperature, pH, salt concentration
Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature decrease enzyme activity because bonds b reak and the enzyme returns to it's PRIMARY structure. (not tertiary)
Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
Changes in temperature and pH can decrease an enzyme's activity by breaking?
Hydrogen bonds
What two internal body conditions effect enzyme activity?
temperature and pH
