Answer from: gomezjuana123

Explanation:

(1). REDUCTION-OXIDATION REACTION:

Energy is derived from electrons in glucose or glucose metabolites.

(2). MAIN REACTION:

Which is the reaction below;

NAD^+1 + 2 NADH + H^+)

In the equation above Glycolysis provides electrons through 2 NADH which is The hormone insulin signals to the cell's plasma membrane to transport, glucose into the cell, Glycolysis means the breakdown of the glucose molecule.The process breaks glucose down into 2 molecules of Pyruvate, Pyruvate is the ionized form of pyruvic acid, Each molecule of pyruvate contains 3 carbons.

(3). KREBS : provision of electrons through 6 NADH and 2 FADH2. The main aim here is to use the pyruvates to produce more ATP. Oxygen plays an important role here.

Water is the by- product.

Electrons power the proteins and the remaining energy from the glucose is released by the electron transport chain.

Answer from: Quest

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
