What connection can be made between enzyme activity and temperature?

Temperature can directly affect enzyme activity. Increases in temperature can cause the enzymes to operate at a quicker pace and cause the enzymatic reaction to move along faster, while decreases in temperatures can cause the enzymes to become sluggish and the reaction to slow down. If temperatures are too high, then the enzymes can fall apart, or denature due to the extreme heat, and if temperatures are too low, then the enzymes can slow down to a complete halt in some cases. Either way, the enzymatic reaction will stop. Most enzymes have an optimal temperature under which they can work the most efficiently and effectively.

Enzymes are proteins that catalyze reactions in biological systems. They are typically complex and "flexible". As molecules, their bonds are subject to excitation. At low temperatures, do not flex enough to let in the substrate. Also, the substrates and enzymes do not move around (brownium motion).However, as temperature increases so does the vibration of the molecules and the chance that the enzyme is "denatured" or broken and in need of repair. So reaction rate increases with temperature until a maximum is met. After the optimum temperature is reached, the denaturing effect of temperature is greater than its effect on reaction rate. This is why the graph shows a gradual increase until the optimum where it suddenly drops off.

Well, the rate at which the enzymes reacted would increase. This would continue as long as temperature rose, up until a point where it is too high that the enzymes will denature and become ineffective. So, if you have ever had a high fever, this is one of the reasons why it is a big deal.
Enzymes will never denature as temperature decreases, though. But, the more the temperature decreases, the slower the rate of reactions.

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
Is temperature a factor that affects enzyme activity?
yes. at low temperature enzymes won't work as effectively, and at high temperature enzymes are denatured.
Temperature and can affect enzyme activity?
Ph level, enzyme concentration, substrate concentration etc
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
What are the relationships between enzymes and temperature?
Enzyme activity increases with temperature, but only up to a point.
What accurately describes how temperature affects enzyme activity?
Enzyme activity increases with temperature, but only up to a point.
Some factors that may influence enzyme activity?

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 is the independent variable between temperature and enzyme activity?
To find out how enzyme concentration affects the activity of the enzyme you must:vary the concentration of the enzyme, by preparing different concentrations (keeping the volume of solution the same)keep the temperature, substrate concentration and pH constantmeasure the activity of the enzyme at each concentrationHow the enzyme activity is measured will depend on the specific enzyme involved.You need to have plenty of substrate (excess substrate) so it doesn't run out during the experiment.In this type of experiment, the enzyme activity is the dependent variable, the temperature, pH and substrate concentration are control variables and the enzyme concentration is the independent variable.
What are factors affecting enzyme activity?
Concentration ( enzyme to substrate ), temperature and pH.
What environment factors can affect the activity of an enzyme?
temperature
Is the enzyme activity same at 5 and 25 Centigrade temperature in water?
The specific activity of an enzyme at a specific temperature will be dependent on both the temperature the enzyme is operating at as well as the concentrations of the substrates (the starting materials of the reaction that the enzyme catalyzes) and products (the end materials of the reaction) present around the enzyme. However, as a general rule, the activity of an enzyme will be different at at 5 centigrade than it will be at 25 centigrade.
How can an enzyme be denatured and why does that process result in the loss of activity of the enzyme?
by increasing the temperature above the optimum temperature(above 45), we can denature an enzyme!! the temperature affects the non-covalent bonds of an enzyme!! at 40
Is temperature a factor that affects enzyme activity?
yes. at low temperature enzymes won't work as effectively, and at high temperature enzymes are denatured.
What determine an enzymes activity?
There are several things that determine an enzyme's activity. The main determinants include the structure of the enzyme, temperature, pH and so much more.
