Question

Draw a hypothetical metabolic pathway in Neurospora crassa composed of five substrates, five enzymes, and a product called nirvana. Number the substrates 1–5, and label the enzymes A–E, in order. (For instance, enzyme A catalyzes the reaction between substrates 1 and 2.) (a) Suppose a mutation made the gene for enzyme C nonfunctional. What molecule would accumulate in the affected cells?

Accepted Answer

Hello everyone. And in today's video we have a problem that may seem long. However, we're going to try to just summarize it in order to make it easier for us to solve it. So we have certain Eurosport cells and these cells are able to grow in these medium called the minimal medium that contains sugar, salt and biotin which is a type of vitamin. Then we have what distinguishes the cell or neuron for a from other organisms allowing it to survive on such a small amount of nutrients. So let's go over answer choices so that we can solve this problem beginning by answer choice B. They do not need other amino assets and vitamins to survive. Well we have that they use biotin so they definitely need access to vitamins as violin is the type of vitamin. So we're going to cancel us out as an incorrect answer choice. Then we have answer choice C They have adapted to the condition where they are grown. Now I'm going to tell you why this is incorrect and the reason for this is that if they do not have the metabolic capabilities to grow here or to sustain themselves here they will not be able to grow, they will just die before they adapt. So this is an incorrect answer choice and we will cancel it out. Then we have d they have mutated into stronger and more resistant types and this is related to immunity and there is not really any type of just prompt here that tells us about mutations that this Eurosport has undergone furthermore, since they're growing in a medium. It is their accessibility or just the metabolic capabilities that they have to access these nutrients and not their immunity that is allowing them to survive. So this is an incorrect answer choice and we will cancel it out. Then we have a they have different biochemical pathways and other organisms and this term this biochemical pathways is nothing more than metabolism. Now these biochemical pathways allow it to process sugar, salt and this biotin, and because of this they're able to grow in these medium with very little nutrients because they have the biochemical pathways in order to process these nutrients. We're going to highlight this as the final answer to our question. I really hope this video helped you and I have to see you on the next
