What else can I help you with?
What best describes chemical equilibrium a reactions have stopped b reactions continue with no effect on the concentration of reactant and products c reactions stop only when a?
B. Reactions continue with no effect on the concentration of reactant and products. Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction, leading to a constant concentration of reactants and products.
What is the effect of light on the rate of dark reaction of photosynthesis?
Light is required to drive the light-dependent reactions of photosynthesis, which produce ATP and NADPH that are used in the dark reactions. In the dark reactions (Calvin cycle), the rate of CO2 fixation and conversion into sugars increases when there is an adequate supply of ATP and NADPH generated from the light reactions, thereby enhancing the overall photosynthetic process.
Factor that effect enzyme function?
Factors that can affect enzyme function include temperature, pH levels, substrate concentration, enzyme concentration, and the presence of inhibitors or activators. Changes in any of these factors can alter the activity of enzymes and either increase or decrease their ability to catalyze reactions.
What three conditions can effect enzyme reactions?
pH level: Enzymes have an optimal pH at which they function, and deviating from this pH can affect their activity. Temperature: Enzymes can denature if exposed to extreme temperatures, reducing their effectiveness. Substrate concentration: Enzyme activity can be influenced by the amount of substrate available for the reaction.
Why do you think increase in 9 degrees above our normal temperature has lethal effect on cells?
An increase in temperature of 9 degrees above normal can denature proteins and disrupt cellular processes in the body. This can lead to cell damage and even cell death. High temperatures can also cause enzymes to lose their shape and function, impairing essential biological reactions.
What effect did photosynthetic cyanobacteria have on earth's environment?
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
How might the photosynthetic organisms counter the greenhouse effect?
Photosynthetic organisms counter the greenhouse effect. This is because plants use carbon dioxide and turns it into oxygen instead. Carbon dioxide is causing the greenhouse effect.
What is the effect of high temperature of current carrying capacity of battery?
The higher the temperature of a battery, the faster the chemical reactions in the battery, and the shorter the battery life span.
What has the author Richard Jason Kirby written?
Richard Jason Kirby has written: 'Photosynthetic activity and acquired thermotolerance in the cyanobacterium, Anabaena sp. PCC7120' -- subject(s): Cyanobacteria, Effect of temperature on, Effect of light on, Anabaena
Are chemical reaction affected by differences in temperature?
Yes, temperature has an effect on the speed of the reaction. Also most chemical reactions create heat. I feel that it is not exactly correct to say that most chemical reaction create heat. That is true for exothermic reactions, which give off heat, but endothermic reactions absorb heat instead.
Why does temperature have little effect on the absorption of light by photosynthetic organisms?
The same can be said about objects, As long as temperature does not change color, composition, or state of the object, they will always reflect (thus also absorb) roughly the same amount of light.
Are the reaction-rate changes recorded in Table 11.4 consistent with the rule of thumb concerning the effect of a 10oC temperature increase on the rate of reactions?
no
What effect temperature?
effect of temperature
What experiment might use temperature as a measurement?
An experiment measuring the effect of temperature on the rate of chemical reactions or the growth of plants could utilize temperature as a measurement. By adjusting the temperature and observing changes in the reaction rate or plant growth, researchers can determine the impact of temperature on these processes.
Photosynthetic organisms may counter greenhouse effect by?
storing CO2 even after they are dead
What effect does temperature have on the reactions occurring in a voltaic cell?
Temperature affects the reactions occurring in a voltaic cell by increasing or decreasing the rate of reaction. Generally, an increase in temperature increases the rate of reaction because the molecules have more kinetic energy and collide more frequently. However, extreme temperatures can also lead to changes in the cell's performance and efficiency.
How does temperature effect kc kp?
The equilibrium constants ( K_c ) and ( K_p ) are affected by temperature due to the principle of Le Chatelier, which states that a system at equilibrium will shift to counteract changes in conditions. For exothermic reactions, increasing temperature decreases ( K_c ) and ( K_p ), while for endothermic reactions, increasing temperature increases these constants. This is because temperature influences the position of equilibrium, favoring either the reactants or products based on the heat exchange associated with the reaction.
