on When testing the effect of substrate concentration on the reaction rate, there comes a point at which increasing the substrate concentration has no effect on the reaction rate. That is, the reaction rate remains the same and no longer increases. Which of the statements below would explain this? Select one: O A. The enzyme is denatured OB. The substrate is denatured OC. All available enzymes are saturated or full with substrates. OD. The enzyme concentration is too high
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?
Which of the statement is true regarding equilibrium?

Which of the following is not a mechanism that enzymes use to lower the activation energy of a reaction?
Many enzyme mechanisms involve transferring protons. Sidechains of an enzyme can act as catalytic acids or catalytic bases in this process. The figure below shows a step in the reaction by the enzyme triose phosphate isomerase. Glu165 group. -OH Would a catalytic acid gain or lose a proton? Which sidechain in the mechanism is acting as a catalytic acid? co CH,OPO, 2- Activity remaining (%) Would a catalytic base gain or lose a proton? Which sidechain in the mechanism is acting as a catalytic base? 100 Curve I 8 Glu¹65 9 Below are two pH rate profiles showing the percent activity as a function of pH. Answer the questions below about how these curves relate to the mechanism of triose phosphate isomerase.

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
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
