All organisms use oxidation-reduction reactions to harness energy, and this newly harvested energy is used to produce atp. oxida

tion is defined as the loss of electrons. reduction is the gain of electrons. the energy in fuel molecules (often carbohydrates) is in the form of electrons. when electrons are removed from their high-energy state in fuel molecules (the electron donors), those molecules are oxidized. the electrons must be added to another molecule, which serves as the electron acceptor. as it gains electrons, the electron acceptor is reduced. when these electrons arrive at the final electron acceptor, they are at a lower-energy state compared to their original position in the electron donor. the goal is to harness the energy the electrons lose during this transfer process. in this activity, you will examine three equations and indicate which reactants are electron donors and which are receptors. in addition, you will identify the oxidized product and the reduced product

1. In first reaction reactant a is the electron donor, while b is the electron acceptor,
the oxidized product is c while the reduced product is d

2. in the second equation e is the electron donor, f is the electron acceptor
g is the oxidized product while h is the reduced product.

3. In the third reaction i is the electron donor, j is the electron acceptor , k is the oxidized product while l is the reduced product.

In the diagram, which letter is altered by a catalyst? <br><br> A<br> B<br> C<br> D
Yanka [14]

Answer:

A

Explanation:

A catalyst refers to an enzyme composed of peptides in their tertiary conformation.  

The addition of a catalyst provides a new path to the reaction and the reaction proceeds in a faster way compared to the reaction without a catalyst.

The peptides are arranged in such a way that they form a pore-like structure which allows the binding of the substrate molecules by forming a temporary covalent bond. These bonds lower the activation energy of the complete reaction which is required to initiate a reaction.

In the given diagram, the activation reaction is represented by the letter "A" and therefore a catalyst will lower and alter the value of A.

Thus, Option-A is correct.

The loops in ptolemy’s heliocentric model , and those shown on the video , are called?
Effectus [21]

Answer:

Retrograde Motion

Explanation:

The theory that the earth revolves around the Sun is called the heliocentric theory, helio meaning 'sun' and centric meaning 'in the center.

' This theory was developed in parts by different astronomers over many years, namely Aristarchus, Copernicus, Kepler, and Galileo.

The reaction from society at the time was that the heliocentric theory was not even worth talking about.

Everyone had evidence to prove that the Earth was the center because if the sun started at one point in the morning and ended at another at night, it was common sense that we were obviously the center.

Copernicus heliocentric theory or it is also named as Sun-centred theory had accepted by Galileo.

The geocentric model is also known as geocentrism.

Determine the empirical formula for a compound that contains 48.6%C, 8.2% H, and 43.2% S by mass.
vagabundo [1.1K]

The empirical formula for a compound that contains 48.6%C, 8.2% H, and 43.2% S by mass is C_3H_6S.

<h3>What is the empirical formula?</h3>

An empirical formula tells us the relative ratios of different atoms in a compound.

We need to calculate the number of moles

Number of a mole of carbon =

48.6 g X (\frac{1 mole }{ 12.0107 g}) =4.05 mole

Number of a mole of hydrogen =

8.2g X (\frac{1 mole}{.00784g}) =8.14 mole

Number of moles of sulphur =

43.2g X (\frac{ mole}{32.065g}) = 1.35 mole

Dividing each mole using the smallest number that is divided by 1.35 moles.

Carbon= \frac{4.05 mole }{1.35 mole} =3

Oxygen= \frac{8.14 mole}{1.35 mole} =6

Sulfur= \frac{1.35 mole}{1.35 mole} =1

Empirical formula is C_3H_6S
