How does high temperature effect photosynthesis?
The rate of photosynthesis depends on temperature the same way enzymes depend on temperature. Photosynthesis involves enzyme assistance. Enzymes are biological catalysts that speed up chemical reactions. Enzymes are affected by pH and temperature. If the pH is too acidic or basic, enzymes will be denatured (which means they will change shape and not be able to catalyze reactions as well or entirely). Same goes for temperature. If the temperature is too cold or too hot, the enzymes might deactivate, or their efficiency will be inhibited. So, if the temperature of the organism's environment is too high or low, the rate of photosynthesis will decrease because the enzymes aren't working properly. On the other hand, if the temperature is optimal for enzyme activity, the rate will increase, as production is at its high.
Why does Enzyme reaction rate decrease at 37 degrees?
Enzymes are catalysts for chemical reactions. All chemical reactions are affected by temperature. Higher temperatures make the reactions happen faster, and colder temperatures make them happen slower. At 37 degrees, just a little above freezing, many biological enzymes practically stop working.
What do high temperatures do to enzymes?
When enzymes are heated to high temperatures they can denature which means that they sort of fall apart as the bonds which hold the amino acids (the molecule that makes up an enzyme) together. when the enzyme denatures it looses its shape and cannot bind with the substrate (the thing it is trying to break down). Almost all enzymes are biochemically active at metabolic temperatures, i.e., mid 30's to 38 degrees Celcius. Moreover, the temperature affects directly to the tertiary and secondary structures disrupting hydrogen bonds, van der Walls and ionic forces
How does the sperm penetrate the oocyte?
Sperm has enzymes that breakdown the outer coat of the oocyte. It takes many sperm with all their enzymes working together to accomplish this.
What are some limiting factors of the photosynthesis process?
The maximum rate of photosynthesis is controlled by the limiting factor. For instance, increasing the temperature from 10ºC to 20ºC could double the rate of photosynthesis as the plant's enzymes will be closer to their optimum working temperature. As the temperature is increased, molecules in the cells will be moving at a faster rate due to kinetic theory. If the temperature is raised above a certain level, the rate of photosynthesis will drop as the plant's enzymes are denatured. They will therefore be more likely to join onto the enzymes and react. But if this happens the plant will need more water or light so they become the limiting factor. Most plants have ways to make up for the insufficient supply of any of them. Most plants grow towards their light source. Also a lot of plants have very deep roots that can make up for insufficient water supply. If a human wanted to increase the yield of a plant they would put up artificial lights, fertilisers to increase minerals in soil and a sprinkler system to keep the plants watered.
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
What happens to enzyme actvitys when temperature rises?
The enzymes will stop working because they only work in certain temperatures.
Difference between hot working process cold working process?
Hot mechanical working operation on the missing piece we do. Mechanical operation of the work we do on a normal cold temperatures.

When does it mean when an enzyme is denatured?
when an enzyme is denatured, it means that it is unable to be functional or active. for example, the enzymes in a flower for it to use photosynthesis work best at around 35 degrees celsius. once the temperature reaches past 60, the enzymes stopp working and the plant no longer is able to produce photosynthesis. denature all in all, denatured is when the enzyme is unable to work
Are enzymes able to heat up molecules so they can react?
Enzymes do not heat up molecules so they can react. Enzymes are catalysts that lower the activation energy of a reaction but are not consumed in the process.
What are the catalyst found in living cells called?
Catalysts that are active working in the body are called enzymes.
Is the ammonia Haber Bosch process dangerous?
Working with gases (especially hydrogen and ammonia) at high temperatures and pressures may be dangerous.
Does the rate of photosynthesis will decrease at a very temperature Why?
The rate of photosynthesis depends on temperature the same way enzymes depend on temperature.Photosynthesis involves enzyme assistance.

What affect does temperature have on cellular enzyme activity?
Enzymes generally work within a given temperature range. As the temperature is increased the activity will increase. However if the optimum temperature is surpassed, the enzymes will stop working.
What are the substances that keep enzymes from working?
inhibitors
