The proteins are the first to assemble in the organelle called the irregular endoplasmic reticulum and then the proteins are transported by an organelle known as the Golgi bodies.

Protein cargo moves from the ER to the Golgi is modified within the Golgi and is sent to various destinations in the cell, including the lysosomes and the cell surface. The Golgi procedure proteins are made by the endoplasmic reticulum (ER) before getting off them to the cell. All channel proteins and carrier proteins allow solutes to cross the membrane without the use of energy is called passive transport, or facilitated diffusion. These proteins, and specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later folded into fully functional proteins. The organelle that transports proteins is called the endoplasmic reticulum.

So we can conclude that the endoplasmic reticulum is responsible for the production of protein and transported by the Golgi bodies.

In the course of chemiosmosis, hydrogen ions build up in the mitochondrion's intramembrane space to produce a significant electrochemical gradient for aerobic cellular respiration.

Protons are pumped through specialized channels in the mitochondrial membranes from the inner to the outer compartment during chemiosmosis. A gradient of proton (H+) is created by the pumping. Protons diffuse through a transport protein called ATP synthase to diffuse down the gradient once it has been formed.

Electrons are transferred from one molecule to another in the electron transport chain, and the energy released during these electron transfers is used to create an electrochemical gradient. The energy held in the gradient is utilized in chemiosmosis to produce ATP.

Answer:

8.59 g/cm3

Explanation:

mass = 535,000 mg = 535,000 x 10^-3 g = 535 g

volume = 62.3 cm3

density = m/V = 535 / 62.3 = 8.58747993579 g/cm3 or 8.59 g/cm3

Mercury's molecules have more mass, Mercury's molecules are spaced closer together

We can argue that density is directly related to mass since density is defined as the ratio of an object's mass to its volume, i.e., the higher an object's mass, the higher its density. Mercury's density will be higher than that of liquid water since it has a higher mass than that of water. Since the molecules of mercury are more tightly spaced from one another than those of a liquid, the latter's molecules exhibit lower forces of attraction. Because an object's force of attraction is directly inversely proportional to its mass, the stronger the force of attraction, the larger the mass, which results in a high density.

Each of the following reactions shows a solute dissolved in water and is classified as a strong electrolyte, a weak electrolyte, or a nonelectrolyte.

Define strong electrolyte, non-electrolyte and weak electrolyte:

The complete dissociation of a substance into ions when dissolved in aqueous solution is known as strong electrolyte.

Whereas the substance that does not isolate completely into ions is known as non-electrolyte.

On the contrary, a substance that partially dissociates into ions when dissolved in its aqueous solution is known as weak electrolyte.

(a) x(s)  → x(aq)

It is a non-electrolyte as no dissociation of ions is taking place here.

(b) cd(aq) ⇌ c+ (aq)   +  d−(aq)

This reaction is in equilibrium state and partial dissociation of ions takes place, Thereofre, it is a weak electrolyte.

(c) yz(s)→y+(aq)   +  z−(aq)

This reaction is in non-equilibrium state and hence complete dissociation of ions taking place here. Thus, it is a strong electrolyte.

From the calculations, the energy of the ultraviolet waves is 1.7 * 10^-33 J.

The term wavelength has to do with the distance that have been covered by a wave. In this case, we are told that the photon is from the ultra violet portion of the electromagnetic spectrum. The question here is that we should find the energy of the  ultraviolet photon having a wavelength of 1.18 x 10^8 m.

Let us now look at the things that we have in the question as the parameters that could be used to solve the problem;

Wavelength of the wave = 1.18 x 10^8 m

Plank Constant = 6.6 * 10^-34 Js

Speed of light = 3 * 10^8 m/s

Now we have that;

The process of standardization involves calculating the precise concentration (molarity) of a solution. One type of analytical process that is frequently employed in standardization is titration. A precise volume of one chemical is reacted with a known quantity of another substance in a titration.

The endpoint of a titration is the point at which the reaction is finished. The endpoint is indicated (signaled) using an indicator chemical substance. Phenolphthalein is the indicator utilized in this experiment. Organic compound phenolphthalein is colorless in acidic solution and pink in basic solution.

In this standardization, a sample of potassium acid phthalate (KHP; HKC8H4O4) will be titrated with a sodium hydroxide solution (NaOH) to measure the molarity of the NaOH.

HKC8H4O4 + NaOH -----> NaKC8H4O4 + H2O

(1.502 g KHP)(1 mol / 204.23 g KHP ) = 6.267 x 10-4 mol KHP
