Works by increasing activity in certain areas of the brain to increase concentration and wakefulness?

Orexin increases activity in certain areas of the brain to increase concentration and wakefulness. Orexin reacts with norepinephrine neuron receptors.


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.


How do concentration affect rate?

Increasing the concentraion the reaction rate increase.


In the reaction 2SO2 plus O2 Reversible 2SO3 which change would cause the greatest increase in the concentration of SO3?

Increasing the concentration of either SO2 or O2 would drive the reaction towards the formation of more SO3, resulting in an increase in the concentration of SO3. Increasing the temperature, however, would cause the greatest increase in the concentration of SO3 as it favors the forward reaction which produces more SO3.


How pro duct concentration affect enzyme activity?

Increasing substrate concentration can initially increase enzyme activity as more substrate molecules are available for the enzyme to bind to. However, at a certain point, the enzyme becomes saturated with substrate molecules and enzyme activity levels off. Very high substrate concentrations can also lead to competitive inhibition or product inhibition which can inhibit enzyme activity.

Does increasing the ethylene concentration ripen fruit more quickly?

yes increasing ethylene concentration increase speed to ripe.


How do concentration affect rate?

Increasing the concentraion the reaction rate increase.


Why does increase enzymes concentration promote enzyme activity?

Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.

What is the effect of increasing the concentration of enzymes in a reaction?

If the reaction speed has not already peaked, then it will increase


What are two ways to increase the rate of diffusion?

Two ways to increase the rate of diffusion are by increasing the concentration gradient, which is the difference in concentration between two areas, and by increasing the temperature, which will boost the energy of the particles and thus their movement.


Does increasing concentration increase the rate of reaction?

increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react


What is a drug that increases alertness?

Caffeine is a common drug that is known to increase alertness and improve concentration. It works by blocking the action of a neurotransmitter called adenosine in the brain, which helps to promote wakefulness.

What would increase reaction rate?

raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
