What can Tobin conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess substrate?

There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.

∙ 12y agothe higher the enzyme concentration, the faster the reaction rate. Is is a directly proportional relationship. If enzyme concentration goes down, so does the rate - and vice versa.

What factors affect the rate of enzyme activity?
-Heat, temperature, &pHtemperature, pH level, concentration of enzyme, concentration of substrate( my sec.1 science book)
What are 3 factors which can influence the activity of an enzyme?
temperature, PH and concentration of substrate (reaction).
What three conditions can effect enzyme reactions?
1. Temperature (high temperature might denature an enzyme) 2. Concentration of substrate 3. Presence of a catalyst
What scientists conclude from the presence of myosin in both humans and yeast?

What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.

What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
No change in enzyme activity would be observed.
What happens if the enzyme concentration is low?
An enzyme can overcome the presence of a competitive inhibitor by increasing the substrate concentration The reaction rate falls direct propartional to the concentration fall (which is the result of that same reaction). This is called 'first order reaction rate'.
What are 3 factors which can influence the activity of an enzyme?
temperature, PH and concentration of substrate (reaction).
What modify's the rate of enzyme activity.?
Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activator
Turning genes on in response to the presence of substrate is called?
Induction

What is the relationship between asparagine and glutamine?
Asparagine and glutamine share some characteristics, i.e., they are nonessential polar and uncharged amino acids. The most important feature that they share is in the asparagine synthesis. Asparagine comes from the aspartate as substrate of the asparagine synthetase enzyme that incorporates an glutamine molecule to provide an amino group to the substrate, leaving glutamate from the reaction, and in presence of ATP as energetic group.
What affectts the speed of a chemical reaccion?
Temperature, concentration, presence of a catalyst.
