according to the graph what condition is best for enzyme activity?
According to the graph 40 Celsius degrees is the better condition for enzyme activity because it increases the rate of reaction.
What is the rate of reaction?The rate of reaction refers to the conditions in which an enzyme is working in order to convert given reactants into one or more products of such chemical reaction. This rate is very variable depending on the intrinsic properties of the enzyme and environmental factors that alter its activity.
In the image, we can observe that the enzyme has differential rates of reaction depending on the temperature.
Therefore, we can conclude that the rate of reaction of an enzyme largely depends on the condition in which the enzyme works such as in this case the temperature factor.

A typical mechanism of disease development and a prognostic factor for malignant tumors is developed resistance to prostate cancer treatments. Resistance to MTAs, such as the taxane Docetaxel, determines treatment failure and the progression of the disease into lethal stages.
The variety of processes causing acquired resistance has been investigated for decades, but they remain poorly understood, which severely restricts the creation of novel therapeutic approaches. We outline a procedure for creating Docetaxel-resistant prostate cancer cell lines in this article.
The Docetaxel-resistant cell lines created by this method have been successfully used in recent studies, such as the loss of resistance properties over time, and they present an opportunity to enhance our knowledge of the molecular mechanisms behind acquired chemoresistance in deadly prostate cancer.

15. Choose two objects of different weights that can be thrown into the air. The objects are
thrown with the same amount of force. Determine which object has more kinetic
energy and explain why.
Now suppose both objects are to be rolled down a slide. What could affect the kinetic
energy so that the other object now has more force? Explain your reasoning.
The object which is having greater mass will have greater KE if gravity is neglected. Cause kinetic Energy is directly proportional to the mass of the object.
Rolling down the slideNow on rolling down the slide the one which is rolled from a greater height will have greater potential energy will eventually have greater kinetic energy.
The energy that an object has as a result of its ongoing motion is known as kinetic energy in terms of physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
The body holds onto the kinetic energy that it acquires during this acceleration until and unless its speed changes. Kinetic energy has the following formula: K.E. = ½ m v2, where m is the object’s mass and v are its square velocity.
Measure of Kinetic EnergyThe kinetic energy that is measured in kilograms-meters then squared per second squared if this mass is then measured in kilograms and the velocity is then measured in meters per second.
When potential energy is released, among other catalysts such as elastic forces or gravity, kinetic energy is produced.
Motion is created by kinetic energy. The kinetic energy of an object increases as force is applied to it and it accelerates.

4. What determines the structure of the catalase molecule?
Answer:
The catalase reaction is dependent on the substrate concentration. If you have an excess of enzyme but not enough substrate, the reaction will be limited by the substrate availability.
The activity of catalase enzymes determines the structure of catalase molecules. This is because it has two enzymatic activities and depending on the concentration of hydrogen peroxide, it has to change its structure.
What is the function of the catalase enzyme?The function of the catalase enzyme is to accomplish neutralization through the process of decomposition of hydrogen peroxide. Due to this, the optimum level of molecules is maintained within the cell.
Catalase enzyme is the key enzyme that is tetrameric in nature and consists of four identical subunits. Each of them contains a heme group and NADPH.
The reaction of catalase significantly depends on the concentration of substrate. For example, if catalase is treated with the excess of the enzyme but not enough substrate, the reaction will be limited by substrate availability.

The salivary amylase does not function once it reaches the stomach after the good from mouth is passed to it.
Salivary amylase is an enzyme that breaks down carbohydrates right in the mouth. When it is passed to the stomach, the acidic ph of stomach denatures this enzymes and causes it to change it's shape. Consequently, the enzyme stops functioning.
Like most other enzymes, salivary amylase is a protein. At a pH between 6.5 and 7.0, it operates most effectively. More acidic or basic environments result in altered protein folding, which reduces the enzyme activity of the molecule.
The stomach's pH is typically between 1.0 and 2.0, which is very acidic. Salivary amylase's protein structure denatures and changes form at this pH level. As a result, when salivary amylase reaches the stomach, it is inactive.

In the presence of oxygen, yeasts consume glucose to release energy; as glucose has a greater rate of respiration, more glucose causes yeasts to respire more quickly. This cellular respiration generates water, energy, and carbon dioxide.
Yeast will produce more carbon dioxide at higher temperatures, which will result in more bubbles developing. The rate of respiration will decrease whenever the temperature rises above a particular level.
