What else can I help you with?
The changing pitch of a police cars siren as it moves by you is an example of what?
The Doppler effect
What conditions would have to be met in order for an ambulance with its siren on not to exhibit the Doppler effect when it passes you?
As far as I know, there will always be a Doppler effect when there is relative movement between the object that emits sound, and the observer (i.e. you, who are listening to the sound).
Of what significance was the Hawthorne effect on employees who participate in scientific studies?
it has been interpreted to mean that when employees feel important and recognized, they exhibit greater motivation to excel in their work activities
What process causes smelly gases to spread around a room on their own?
The process you're thinking of is called "diffusion". It is the property of a substance to travel from a place of greater concentration to a place of lessen concentration. Put simply, a substance will spread itself out in whatever area it's contained in. The effect this has on the smelly gas in the room is that the gas will go from the area of greater concentration (Where the gas was released) to lesser concentration (The rest of the room). Thus, the gas will spread out evenly amongst the air in the room.
What effect do alkalis hava on litmus solution?
If the solution contains acid, then the alkali turns the litmus to its original colour(blue).The color is effected by the concentration of the acid and the alkali.
How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
What effect enzymes activity?
Temperature, pH, substrate concentration
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.
What is the effect of subsrtrate concentration on enzyme activity?
The effect of substrate concentration on enzyme activity is characterized by an initial increase in reaction rate as substrate concentration rises, leading to more frequent enzyme-substrate collisions. However, this relationship reaches a saturation point where all active sites of the enzyme molecules are occupied, resulting in a maximum reaction rate known as Vmax. Beyond this saturation point, further increases in substrate concentration do not enhance enzyme activity, as the enzymes are already working at their maximum capacity. Thus, enzyme activity is dependent on substrate concentration up to a certain threshold, after which it plateaus.
Increasing the substrate concentration in an enzymatic reaction could overcome what?
Increasing the substrate concentration in an enzymatic reaction could overcome low reaction rates due to insufficient substrate molecules available for the enzyme to bind to, thereby accelerating the reaction rate. This is known as the substrate concentration effect, where higher substrate concentrations can lead to higher reaction rates until the enzyme becomes saturated.
What cause competition?
It slows down or even stop the enzymatic activity because it compete the actove site of the enzymes with substrate and its effect can be reduced by concentrating the concentration of substrate or add more subatrate therefore more substrate are compete with the inibitors
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
Increasing the concentration of substrate will not overcome the effect of a noncompetitive inhibitor. The inhibitor binds to the enzyme at a site other than the active site, causing a conformational change that reduces the enzyme's activity. Therefore, increasing the concentration of substrate will not result in a significant increase in enzyme activity.
What effect does changing the concentration of calcium ions have on the coagulation of milk?
the rate of coagulation increases as the concentration of calcium ions increase.
How do you change the concentration of the substrate where the substrate is milk and the enzyme is renin?
i just did this experiment in class today. what you need to do is add water to the milk. but you have to keep the same amount of milk in all of them. this is if you are testing the effect of substrate concentration on renin. so you have one experiment with 8ml of milk and then one with 6 ml of milk and 2 ml of water and 4 ml of mik and 4ml of water and so on ... be carefful to stir the solution a bit i hope this helps
What are the four factors that effect enzyme activity?
The four factors that affect enzyme activity are temperature, pH, substrate concentration, and the presence of inhibitors or activators. Temperature and pH can alter the enzyme's shape, while substrate concentration determines the rate of reaction. Inhibitors and activators can either decrease or increase enzyme activity, respectively.
Is Vmax a threshold of substrate concentration for initiation of an enzymatic reaction?
Oddly phased question in my opinion. Vmax is only effected by the amount of enzyme present in the reaction. Substrate concentration has zero effect on Vmax. There for I believe the answer in no. {Enzyme concentration is responsible for this}
Which of the following variables has the least direct effect on the rate of a hydrolytic reaction regulated by enzymes?
Temperature has the least direct effect on the rate of a hydrolytic reaction regulated by enzymes. Other factors like substrate concentration, enzyme concentration, and pH have a more direct impact on the rate of hydrolysis.
