Are chemical mechanisms that start a reaction. Inhibitors Activators Centrioles Vacuoles?
You think probable to activators for enzymes.
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
activators; inhibitors
Can the presence of inhibitors or activitors affect enzyme activity?
yes, enzymes can be inhibited by other enzymes.
What is the general features of allosteric regulation using the feedback inhibition?
enzymes situated at key steps in metabolic pathways are modulated by allosteric effectors these effectors are usually produced elsewhere in the pathway effectors may be feed-forward activators or feedback inhibitors kinetics are sigmoid ("S-shaped")
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What are 4 factors that can regulate enzyme activity?
pH, temperature, concentration of substrate, incubation period
Are chemical mechanisms that start a reaction. Inhibitors Activators Centrioles Vacuoles?
You think probable to activators for enzymes.
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
activators; inhibitors
When was The Activators created?
The Activators was created in 2009.
What kinds of chemicals might you add to try to speed up the action of an enzyme or to inhibit its action?
The type of chemicals that speed up the action of an enzyme are called activators. Inhibitors, meanwhile, slow down the action of enzymes.
Can the presence of inhibitors or activitors affect enzyme activity?
yes, enzymes can be inhibited by other enzymes.
What factors affect the rate of enzyme activity?
-Heat, temperature, &pHtemperature, pH level, concentration of enzyme, concentration of substrate( my sec.1 science book)
Which regulatory elements are not composed of DNA sequences?
Activators You shoulve at least given us the list :p
What do kidney regulate in the blood?
They help regulate blood pressure (I think)
How do cells regulate enzymes?
There are two ways wherein cells regulate the activity of enzymes. These involve controlling the amount of the enzyme and controlling the activity level of the enzyme.
How does a heart cell knows it's a heart cell?
Cells produce an enormous amount of molecules of which some (many) act as messengers and activators or inhibitors. When heart cells receive stimulation from other heart cells with certain molecules, they "know" what they are and that they should keep on being heart cells.
What is the general features of allosteric regulation using the feedback inhibition?
enzymes situated at key steps in metabolic pathways are modulated by allosteric effectors these effectors are usually produced elsewhere in the pathway effectors may be feed-forward activators or feedback inhibitors kinetics are sigmoid ("S-shaped")
