The half-reactions involved in the lactate dehydrogenase (ldh) reaction and their standard reduction potentials are

1 answer:

5 0

Enzyme lactate dehydrogenase catalyses the conversion of lactate to pyruvate. In this reaction lactate loses two electrons (becomes oxidized) and is converted to pyruvate. NAD+ gains two electrons (is reduced) and is converted to NADH. The half reactions involved are;

NAD+ + H+ + 2e- = NADH -0.320
Pyruvate + 2H+ + 2e- = Lactate -0.185
Giving an overall reaction of;
Lactate + NAD+ = Pyruvate + NADH + H+

Suppose that a person eats a diet of 2391 Calories per day.a.) Convert this energy into J. Express your answer using four signif

alekssr [168]

Explanation:

(a)

The given data is:-

Energy = 2391 Calories

The conversion of calories to J is shown below as:-

1 calorie = 4.184 J

So,

Energy = 4.184 * 2391 J = 10003.944 J

Answer in four significant digits: - $1.000\times 10^4\ J$

(b)

The conversion of calories to kJ is shown below as:-

1 calorie = 0.004184 kJ

So,

Energy = 0.004184 * 2391 kJ = 10.003944 kJ

Answer in four significant digits: - $1.000\times 10\ kJ$

(c)

The conversion of calories to kWh is shown below as:-

1 calorie = $1.1622\times 10^{-6}$ kWh

So,

Energy = $1.1622\times 10^{-6}\times 2391$ kWh = 0.002778873 kWh

Answer in four significant digits: - $0.002779\ kWh$

What is the molarity of a strong acid solution with a pH of 3?

Anna35 [415]

Answer:

Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.

Arrange the following in order of increasing melting point: NaCl, H2O, CH4, C6H4(OH)2.

aliina [53]

Explanation:

one thing to know is that higher surface area = higher boiling point.

NaCl has the smallest surface area, so it's the first one.

H2O has less surface area than methane, so it's second.

Methane has more surface area than H20, so it's third.

The big molecule has the most surface area, so it's last

The lifetime of a human is approximately 71 years. Which of the following is this number closest to? Remember the following conv

jarptica [38.1K]

2.2Giga

Explanation:

Given that the number of years = 71years

We need to convert this to seconds;

60s = 1 min

60 min = 1hr

24hr = 1 day

7 days = 1 week

52 weeks = 1yr

71 years x $\frac{52weeks }{1yr} x \frac{7 days}{1 week } x \frac{24hr}{ 1day } x \frac{60min}{1hr} x \frac{60s}{1min}$ = 2,232,921,600‬s

This value is 2.2 x 10⁹s = 2.2Giga
