The atoms in a chemical reaction are responsible for the mass energy temperature explosion

Mass

Mass is something that can be converted into energy according to the Eisenstein formula. So if there is no mass there is no energy. Similarly the mass of atoms makes them matter as we say that matter is something having mass and occupy space. In the same way temperature is also a quantity which is produced by collision of atoms. In short mass of matter is responsible for energy, temperature and explosion.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
