Krebs Cycle experiment: if you want to increase the rate of the succinate forming fumarate, what could you do to the experiment?
Sergio [31]

To increase the rate of the succinate forming fumarate you can increase the ATP and the enzyme that catalyzes this reaction

The Krebs cycle, also known as the citric acid cycle comprises a set of chemical reactions that are essential for organisms to obtain energy.

One of the steps in the cycle involves the use of succinate with a chemical formula of C4H6O4 to form fumarate or C4H4O4. This means in this reaction it is necessary to remove 2 hydrogen atoms.

This process requires two main factors:

  • ATP or energy the cell uses to carry out the reaction
  • Succinate dehydrogenase or the enzyme that removes the hydrogen atoms

Based on this, the reaction can be faster if there is more succinate dehydrogenase or if the energy increases.

A 62.2-kg person, running horizontally with a velocity of 3.80 m/s, jumps onto a 19.7-kg sled that is initially at rest. (a) Ign
jek_recluse [69]

Answer:

a) v = 2.886\,\frac{m}{s}, b) \mu_{k} = 0.014

Explanation:

a) The final speed is determined by the Principle of Momentum Conservation:

(62.2\,kg)\cdot (3.80\,\frac{m}{s} ) = (81.9\,kg)\cdot v

v = 2.886\,\frac{m}{s}

b) The deceleration experimented by the system person-sled is:

a = \frac{\left(0\,\frac{m}{s} \right)^{2}-\left(2.886\,\frac{m}{s} \right)^{2}}{2\cdot (30\,m)}

a = -0.139\,\frac{m}{s^{2}}

By using the Newton's Laws, the only force acting on the motion of the system is the friction between snow and sled. The kinetic coefficient of friction is:

-\mu_{k}\cdot m\cdot g = m\cdot a

\mu_{k} = -\frac{a}{g}

\mu_{k} = -\frac{\left(-0.139\,\frac{m}{s^{2}} \right)}{9.807\,\frac{m}{s^{2}} }

\mu_{k} = 0.014
