Consider a muscle cell with a mutation in Complex I of the ETC resulting in its complete inactivation. How many ATP molecules will this mutated cell produce per glucose molecule fully oxidized?

The standard reduction potentials ( E’ °) for the half reactions are given ​ Fumarate + 2H++ 2e– → succinate E’° = +0.031 V FAD + 2H+ + 2e– → FADH2 E’° = –0.219 V ​ If succinate, fumarate, FAD, and FADH2 , all at 1 m concentrations, were mixed together in the presence of succinate dehydrogenase, what would happen initially?

Choose the wrong statement concerning the ATPase binding-change mechanism.

Predict the output of the following C program: #includeunion u {    struct{        char a, b, c;    }s;    char string[10];} element;main() {    strcpy(element.string, “Hello!”);// copies one string into another    element.s.b = ‘i’;    element.s.c = ‘?’;    printf(“%.3s, %c”, element.string, element.s.a);}

Suppose you discovered a mutant yeast whose glycolytic pathway was shorter because of the presence of a new enzyme catalyzing the reaction glyceraldehyde 3‑phosphate + H2O + NAD+ ⟶ NADH + H+ + 3‑phosphoglycerate Which of the following would you expect to find in the growth metabolism of the mutant yeast?

Write all the different possible outputs of the following Java multi-threaded program: class Test extends Thread {    private int inc;    public Test(int inc) {        this.inc = inc;    }    public void run() {         for(int i = 0; i < 3;i++)                     Main.x += inc;         System.out.print(Main.x);     } } class Main{     public static int x = 0;     public static void main(String[] args){         new Test(1).run();         new Test(-1).run();     } }
