Why is it important that cells maintain homeostasis in order for enzymes to work properly?
Homeostasis is important for our system to be functional!, for example our body maintains 37 degree Celsius inside. So cellular enzymes require the same temperature to carry out biological reactions, if it drops to 30 degrees and we don't have homeostasis to bring back 37 degrees, then most of the enzymes that need 37 degrees would be poorly active.
How does pH affect an enzyme?
When the pH level rises, the enzyme's bonds become weakened, changing the enzyme's structure and disabling its function (so its substrates can't enter its active site). Enzymes, like all proteins, are folded into three-dimensional shapes (called tertiary structure). Their structures are determined by their amino acid sequences and the conditions of the solution they're in. The acidity of a solution can affect the tertiary structure of the protein, making it more or less accessible to the substrates or ligands(molecules that affect enzyme activity but are not processed by the enzyme). In most cells, enzymes acting in the cytosol and mitochondria have pH optima of around 7.2 (physiological pH). However, some enzymes in these compartments actually work better at lower pH, which occurs when the cells are stressed. The vacuole and apoplastic space (between plasma membrane and cell wall) of plant cells is much more acidic, therefore enzymes acting there have pH optima between 3-5. In the human digestive tract, there are enzymes operating at basic pH (mouth and intestine) and highly acidic pH (stomach). So the effect of pH depends on the "native" conditions that the enzyme is optimized to use.
What happens to proteins in the human body when they are heated up above 40 degree celsius why is this dangerous?
When proteins are heated above 40 degrees Celsius, they can denature, meaning their structure changes and they can lose their function. This is dangerous because many proteins in our body have specific structures that are critical for their roles in processes such as metabolism, immune response, and muscle function. Denaturing these proteins can lead to their dysfunction and potentially disrupt normal bodily functions.
Tess has second- and third-degree burns on her arms and face Explain why the burns that Tess suffered make her very susceptible to infection?
Second- and third-degree burns damage multiple layers of skin, compromising the body's natural barrier against infection. The exposed underlying tissue is more vulnerable to invasion by harmful bacteria, leading to an increased risk of infection. Additionally, the healing process for burns can be slow, further prolonging the period of susceptibility to infection.
What is an imaging technique that produces colors to indicate the degree of metabolism or blood flow in the brain is called?
The imaging technique that produces colors to indicate the degree of metabolism or blood flow in the brain is called functional magnetic resonance imaging (fMRI). It measures brain activity by detecting changes in blood flow.
What effect does cooking have on enzyme activity?
You mean heating the enzymes? heating to a certain degree increases their rate of catalytic activity, until about 30-40 degrees Celsius. However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.
How to Write my name with business degree?
What? Please explain.
What is the optimum temperature for enzyme activity in the body?
The optimum temperature for enzyme activity in the body is typically around 37°C (98.6°F), which is body temperature. Enzymes function best within a narrow temperature range, and deviations from this temperature can result in decreased enzyme efficiency or denaturation.
How do you explain one who has one Ba degree and master degree but two degree are from different stream?
There is no reason for that to need any explanation!

What effect do temperature and pH have on enzyme controlled reactions?
Temperature and pH can greatly impact enzyme activity. Enzymes have an optimal temperature and pH at which they function most effectively. High temperatures can denature enzymes, reducing their activity, while extreme pH levels can also affect enzyme structure and function. Changes in temperature or pH outside the optimal range can slow down or even stop enzyme-controlled reactions.
How are depressants classified?
is depreesants classified according to the degree they decrease cns activity
What kind of activity could you do in 15 degree Fahrenheit weather?
Ice-fish
Degree of flexibility older adults have is affected by?
present lever of physical activity
What are some factors that may influence enzyme activity?
Factors affecting enzyme activity1: Enzyme concentrationIf the quantity of enzyme is doubled, the enzymatic activity will also be doubled because more enzymes are now available to work. After a certain level of enzyme concentration, there will be no more increase in the enzymatic activity because all the substrate molecules are combined with an enzyme and the rate of reaction will stabilize.2: Substrate concentrationBy increasing substrate concentration, enzymatic activity increases. Increasing the substrate further without increasing the enzyme concentration will not affect the enzymatic activity because all the enzymes are occupied by a substrate molecule.3: pH valueSome enzymes require acidic surroundings, most require a more neutral condition for their activity. Change in the pH can change the enzyme's structure and enzyme become useless.4: TemperatureAn increase in temperature of 10 degree celsius doubles the enzymatic activity. Each enzyme has its own optimum temperature at which its enzymatic activity is maximum. Very high temperatures break the bonds that maintain shape of enzyme. If the enzyme denatures, the substrate can not fit in to the active sites and enzyme become useless.
Is it possible to attain a temperature less than zero degree kelvin explain?
No.To explain requires many years of education
What temperature do emzymes work best?
the enzymes work best at 37 degree celsius in your body-it depends on the organism you talk about.
