the free energy for the oxidation of glucose to co2 and water is -686 kcal/mol and the free energy for the reduction of nad to nadh is 53 kcal/mol. why are only two molecules of nadh formed during glycolysis when it appears that as many as a dozen could be formed? the free energy for the oxidation of glucose to co2 and water is -686 kcal/mol and the free energy for the reduction of nad to nadh is 53 kcal/mol. why are only two molecules of nadh formed during glycolysis when it appears that as many as a dozen could be formed? there is no co2 or water produced as products of glycolysis. most of the free energy available from the oxidation of glucose is used in the production of atp in glycolysis. glycolysis is a very inefficient reaction, with much of the energy of glucose released as heat. most of the free energy available from the oxidation of glucose remains in pyruvate, one of the products of glycolysis.
There are only two molecules of NADH formed during glycolysis Since most of the free energy generated during glucose oxidation remains in pyruvate, only two NADH molecules are formed.
The overall reaction process of glycolysis is:
Glucose + 2 NAD+ + 2 ADP + 2 Pi ⇒ 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP
From the above glycolytic process, oxidation of glucose produces 2 NADH and 2 molecules of ATP. increase. Since most of the energy stays in 2 molecules of pyruvate, only 2 molecules of NADH are formed during the entire process of glycolysis. The free energy generated during oxidation of glucose remains in pyruvate.
Most of the free energy available from the oxidation of glucose remains in pyruvate, one of the products of glycolysis. Glycolysis refers to the breakdown of the glucose molecules during the complex process of cellular respiration. The process takes place in ten enzymes catalyzed reactions that form the 2 molecules of pyruvate.
The glycolysis process releases a lot of energy which is measured as -686 kcal/mol. The energy is not released into the reaction directly but is conserved in pyruvate form and less is released into driving the reduction of NAD to NADH.

How many calories are needed to convert 1 g of liquid water at 10°c to solid ice at 0°c?.
The calories needed to convert liquid water is 90 calories.
The calories needed by the system depend on the heat released. The total heat received by the system will equal to total heat released by objects. It should follow
Q released = Q received
The heat can be defined by
Q = m . c . ΔT
where Q is heat, m is mass, c is the specific heat constant and ΔT is the change in temperature.
The given parameters are
m = 1 g
T = 10 °C
T' = 0 °C
c = 1 kal / g °C
L = 80 kal / g
Find the change in temperature
ΔT = T - T' = 10 - 0 = 10 °C
Find the calories needed to change temperature until 0 °C
Q = m . c . ΔT
Q = 1 . 1 . 10
Q = 10 calories
Find the calories needed to change water into solid ice
Q = m . L
Q = 1 . 80
Q = 80 calories

Which scientist first proposed that the electron in the hydrogen atom can have only certain energies?.
The idea that an electron in a hydrogen atom can only have specific energies was first put out by Niels Bohr.
Niels Bohr was renowned for what?The Nobel Prize for 1922 was given in recognition of his study on the atomic structure. Since 1930, more and more of Bohr's activities at his Institute have been focused on studying the atomic nuclei's composition as well as their transmutations and disintegrations.
In his model of the atom, Niels Bohr used electrons that could only have exact solid orbits. The quantum concept was initially included into this atomic model. Due to the fact that hydrogen emits and absorbs light at particular wavelengths, that electron may wish to best arise in particular orbits.
Based on the notion that some physical quantities can only assume discrete values in the quantum world, Niels Bohr developed a principle for the hydrogen atom. In his desk-bound state theory, Bohr postulated that electrons no longer radiate energy as they orbit the nucleus but rather reside in states of constant energy. Bohr's artwork was entirely modified in response to the emission spectra of hydrogen.

How does the volume of a real gas compare to the volume of an ideal gas at high pressure?.
According to the Kinetic theory of gases, the volume of ideal gases is negligible compared to the volume of the container. Whereas, the volume of real gases cannot be neglected.
What is kinetic theory of gases?According to the Kinetic theory of gases, matter is made of tiny particles. These particles are not exerting any intermolecular force of attraction or repulsion.
The gaseous particles exerts a pressure by collision to other particle and with the wall of the container. At high pressure, as per Boyle's law for ideal gases, the volume of the gases decreases.
However, Boyle's law cannot be applicable to real gases at all temperature. As the temperature increases, the volume also increases. Moreover, when the volume of particles is reduced, they haven't enough space to move.
Therefore, at lower volume, particles definitely experience an intermolecular force of attraction or repulsion. But this is not considered in the ideal gas theory.

Answer: endoplasmisc reticulum
Explanation:
What is determined by the distance at which the lowest potential energy is achieved and the distance at which positive charges have the least repulsion?.
As the atoms approach one another, the positive charges in the two nuclei begin to reject one another, increasing the potential energy. The bond length is determined by the distance at which the lowest potential energy is reached.
The bond length is determined by the internuclear distance at which the potential energy minimum occurs. The equilibrium bond length, which captures the distance at which the two atoms bounce due to thermal motion, is a better phrase. In general, shorter bonds result in stronger bonds.
The bulk of atoms obtain a lower potential energy when they are bonded to other atoms. The potential energy of the system is said to be zero at this distance.

Warmer temperatures will more water evaporate and will lead to more clouds. These clouds will shade the earth the sun, leading to cooler temperatures.
Explain the term water evaporation.
A type of vaporization called evaporation takes place on the surface of a liquid as it transitions into the gas phase. When humidity impacts the rate of evaporation of water, for example, a high concentration of the evaporating component in the surrounding gas considerably slows down evaporation. Depending on how they collide, the liquid's molecules transfer energy to one another during collisions. A molecule at the surface will escape and turn into a gas when it has enough energy to outpace the vapour pressure. Evaporation results in cooling because the energy from the evaporated liquid is lost, which lowers the liquid's temperature.
