Textbook Question
Chapter 14.1, Problem 1CC
MAKE CONNECTIONS In a research article about alkaptonuria published in 1902, Garrod suggested that humans inherit two “characters” (alleles) for a particular enzyme and that both parents must contribute a faulty version for the offspring to have the disorder. Today, would this disorder be called dominant or recessive? (See Concept 11.4.)

Briefly describe why mammals can not convert fatty acids to carbohydrates?
Why plants can do so? What are the secret weapons for plants to so? Briefly describe enzyme names and pathway? Based on this knowledge, what is your strategy to make a mouse is able to do so?
. MAKE CONNECTIONS Considering how enzymes function (see Concept 8.4), explain why vitamins are requiredin very small amounts.
5) Consider the hypothetical biochemical pathway shown below. Assume that each letter (A, B, C, etc) represents a molecule and each number over an arrow (1, 2, 3, etc) represents an enzyme that catalyzes that reaction (so enzyme 2 catalyzes the conversion of B to C). Indicate all the probable feedback inhibition interactions that would be expected to regulate the activity of enzymes in this pathway. please indicate each interaction in the format example: "X will inhibit enzyme 27".
