Answer:
cellular respiration
Explanation:
All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen. There are therefore two types of breathing: aerobic respiration and anaerobic respiration. The latter also called fermentation.
Aerobic respiration (oxidative phosphorylation)
- Use molecular O2.
- It degrades glucose to CO2 and H2O
- Exergonic
- Recovers about 50% of chemical energy
- Present in most organisms.
- It uses enzymes located in the mitochondria.

Answer: it is a curve line that resembles a hill, where the reactants start at an intermediate height (on the left side), the activated complex is at the peak, and the products are in the through (the lowest level) at the right side.</span><span />

<span>1)
The potential energy diagram shows the potential energy of the spieces in the vertical axis, as they progress from the reactants to the products (algong the horizontal axis. The horizontal axis represents the progress of the reaction.
The reactants are in the left extreme of the graph, the activated complex is in the middle, and the products are in the right end.2) In any chemical reaction (either exothermic or endothermic), the products are at a certain energy level that is below the energy level of the activated complex.
The acitvated complex is at the ighest energy level (the peak of the curve) , which is the activation energy, this is the energy required to the reaction proceed from the reactants to the products.

<span>3) Since an
exothermic reaction releases heat (energy) the energy (enthalpy) of the products is lower than the energy of the reactants. That is why the right end of the curve is lower than the left end.

Since, one image is worther than one thousand words, I attache a picture of the energy graph for an exothermic reaction.
See the figure attached.

Answer:
Iodine (I)
Explanation:
The atomic mass of Arsenic (As) is 74.92 amu. Also, we know that Halogen Group consists of following elements.
Fluorine, Chlorine, Bromine, Iodine, Astatine and Tennessine
And in given four options only Chlorine and Iodine belongs to halogen family. And we know that the atomic mass of chlorine is 35.45 amu which is less than that of Arsenic, therefore Iodine with atomic mass of 126.90 amu is the correct answer.
Using the ISU to describe motion is important because it is simple system of measurements and easy to use
That is -273 + 30 = -243 degrees celsius
