Some research has indicated that a lack of catalase can lead to the development of type 2 diabetes. It seems that some other molecules within living organisms are able to sufficiently break down hydrogen peroxide—enough to sustain life. The toxic nature of hydrogen peroxide also makes it a powerful disinfectant. And in conclusion from the information ive found ,catalase functions best at around 37 degrees Celsius as the temperature gets colder or hotter than that, the ability to work will denature and the enzyme will be

Zygotene: Synapsis, process of chromosome pairing, caused the visible association of homologues with one another. It is accompanied by the formation of a complex called synaptonemal complex, a ladder-like structure with transverse protein filaments connecting the two lateral elements. Pachytene: By the end of this stage, genetic recombination would be completed under the facilitation of enzymatic machinery from the recombination nodules, located within the center of the synaptonemal

The majority of marine organisms use Coelenterazine in the process of bioluminescence. However, the only difference between each organism’s reaction is the type of luciferase each organism uses. Coelenterazine is used along with photo-proteins by Hydrozoans, Ctenophores, and Radiolarians. Coelenterazine is also well known for the fact that it is the light emitter of Aequorin. Aequorin was the first known photo-protein.

Similarly, a slower decrease in absorbance corresponds to a low rate of reaction. Through altering the various concentrations of NaCl that Amylase is exposed to, the effect of different NaCl concentrations on rate of reaction of amylase can be determined. Research Question: What are the effects of different sodium chloride concentrations on the rate of reaction of amylase, measured the spectrophotometry. Hypothesis: Sodium chloride, temperature, pH levels are all conditions that affect the activity of an enzyme. These conditions may denature the enzyme, decreasing its rate of reaction.

The activity of an enzyme is affected by its environmental factors, and any change results in an alteration in the rate of the reaction caused by the enzyme (2). Naturally, the enzymes are adjusted by producing optimum rates of reaction or they adapt to function well in extreme conditions (2). Temperature, pH, and enzyme and substrate concentration all affect enzyme activity. The rate of reaction of an enzyme catalyzed reaction is affected by the difference in enzyme and substrate concentration. Increasing substrate and enzyme concentration will increase the rate of the reaction because more substrate molecules will be colliding with enzyme molecules, resulting in products being formed (1).

Endocytosis brings molecules into a cell while exocytosis takes molecules out of a cell.2. Both processes use vesicles for molecular transport.3. Endocytosis creates vesicles while exocytosis can destroy them.4. The primary function of endocytosis is getting nutrients and the primary function of exocytosis is expelling waste.Read more: Difference between Exocytosis and Endocytosis | Difference Between

Its role is to act as a medium in the cell. The cytoplasm has a large amount of organelles also known as little organs. Large protein molecules called enzymes are found in both the cytoplasm and in the organelles. Enzymes carry out many chemical reactions in order to create energy, they also transform raw materials into useful substances, or break down old proteins to be recycled. The cytosol in a cell does more than just suspend the organelles.

Cell Division As a eukaryotic organism grows, cells divide and create new cells based on its DNA. This is called cell division. Cell division is the process when a parent cell divides into two or more daughter cells. Cell division occurs as part of the cell cycle. The two types of cell division processes are mitosis and meiosis.

If the temperature, pH and enzyme concentration is kept constant then the rate of reaction will start to decrease as well as the hydrogen peroxide concentration. Aim: To investigate the effects of changing the concentration of the enzyme catalase that it has on the rate of breaking down the Hydrogen Peroxide solution. Dependant and Independent Variables: The Dependent Variables: Amount of time it takes when the bubbles start to rise till when they stop. The Independent Variable: Amount of Hydrogen Peroxide solution. The Controlled/ Fixed Variables are: • The amount of hydrogen peroxide inserted in each test tube.

In plant and fungi, microtubule organizing centre is called as Spindle Pole Body (SPB). All these microtubule organizing centers contain universally a tubulin homologue called γ-tubulin that interacts with α- and β-tubulin and helps in the nucleation of microtubule. In a cell, individual microtubule elongates and shrinks back or may completely disappear and is replaced by a new one. This process involves the polymerization and depolymerization with the hydrolysis of GTPs. The microtubule containing ADP-tubulin at the end is highly unstable and depolymerizes rapidly that is called “catastrophe” and the phenomenon is known as “dynamic
