Sandra is a 30-year-old woman. After medical images and blood tests, Sandra's mother has just been diagnosed with breast cancer. Her mother's mother died of breast cancer several years ago. Should Sandra be concerned that she might be at higher risk for breast cancer herself? O Yes. While there does not seem to be a genetic link with breast cancer, she has been exposed to the same environmental factors as the rest of her family Yes. Some forms of breast cancer have been linked to a gene mutation which she may have inherited from her mother's side of the family O No. The causes breast cancer have not been completely identified so she is probably at no greater risk than any other woman in the population O No. Detection of and treatments for breast cancer have improved so dramatically in recent years that it is unlikely she would develop breast cancer
A dichotomous key works by determining positive and negative reactions to different biochemicals. Why does this method allow us to identify one species of organism from another? – for this question, do not describe the dichotomous key procedure, think about why it works, what are biochemical reactions based on? Think enzymatic pathways, what are enzymes, what are they a reflection of? Keep the answer between 2-3 sentences

Another of the six enzyme classes is which of the following? enzymes catalyze. These classes include the transferases, isomerases, and ligases. All enzymes can be categorized in one of six major classes based on the reactions the proteases kinases hydrolases phosphatases endonucleases An important factor that influences the rate of a biochemical reaction is the temperature. Raising the temperature of a biochemical reaction has which effect upon the kinetics of the reaction? a) b) c) d) e) increases the free energy of the reactants increases the free energy of the transition state decreases the free energy of the reactants decreases the free energy of the transition state decreases the free energy of the products
. To catalyze a biochemical reaction, an enzyme typically dissociates into additional reactant molecules, thereby increasing the геaction ratе decomposes and releases energy to increase the number of successful collisions between reactant molecules binds temporarily to reactant molecules to lower the activation energy of the reaction drives the reaction to completion by consuming byproducts of the reaction CLEAR ALL
The line does not cross the X-axis when the Y-variable is equal to zero 1점 because * Why does this line not start exactly at (0,0)? Rate of Reaction Enzyme Concentration the low concentration of enzyme is still enough to catalyze some reaction some small amount of product can be formed even without the enzyme present some small amount of product can be formed even without any product the pH was changed
A biochemist wants to determine the effect of inhibitor A to enzyme B which catlyzes the conversion of C to D. The effect of A to the rate of formation of D is shown below: 1. The Km (report to the nearest whole number) for the enzyme-catalyzed reaction in the absence of inhibitor A is _____ mM. 2. The Km for the enzyme catalyzed reaction in the presence of inhibitor A is ____mM. 3. The Vmax for the enzyme catalyzed reaction in the absence of inhibitor A is ____ mM/min 4. The Vmax for the enzyme catalyzed reaction in the presence of inhibitor A is ____mM/min 5. Inhibitor A is a/an ________ inhibitor of enzyme B
I was given a graphing activity. It was do with the measuring the reaction rate against temperature. As you can see in the images below when I plotted them it required to be a curved graph. My question is when you have to graph data like the worksheets attached do you simple go through each one or do you have to do something like a curve of best fit. I was also required to interpolate missing dataSpecifically I had to graph the rate of reaction which was measured at mm/s against temperautre. This was for a biology test. The data point were similar to these worksheets in the sense that none of the data points were overallping thy were clearly separated and at different height. BTW this subject was biology.
