The correct answer is: D) excited
A molecule is in an excited state when its energy level is higher than the ground state. That molecule stays in excited state for short time and then returns to a state with lower energy. This return to a lower energy level is described as decay and is the inverse process of excitation.
The transition from ground to excited state of an atom is possible if electrons gain energy that is higher than the difference in energies between the two energy orbits.
Answer:
Cells contain DNA that controls the production of proteins. (2) DNA is composed of proteins that carry coded information for how cells function. (3) Proteins are used to produce cells that link amino acids together into DNA. (4) Cells are linked together by proteins to make different kinds of DNA molecules.
Explanation: Hope this helps!! :)
The answer is: D - glucose.
Explanation:
Water, mitochondria, and glucose are all required for both anaerobic respiration and aerobic respiration.
Enzymes are converted into products by the reactions they catalyze. One enzyme can catalyze many different reactions. ... They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.
