Explanation:
Metals have various properties and are widely used in various application purposes. Metals have good conductivity and ductility property for which they are used in electrical wires like copper. They have good luster because of which they are used in mirrors.
Similarly, tungsten is used in the filament of the bulb because of the properties like electrical conductivity, ductility and high melting point. Thus the filament does not melt even if the heat production is high.

Answer:
compounds involve in glycolysis: glucose, ADP, ATP, NAD, NADH, O₂ and CO₂.
Output: coenzyme A, acetyl CoA.
Explanation:
Glycolysis is the process where a molecule of glucose is discomposed into two molecules of pyruvate to give energy to the cell. It can be divided into two big steps. The first step requires energy and the second step releases energy.
<u>fist step:</u>
The glucose with the help of 2 ATP that will lost a phosphate and become ADP will be transformed into fructose -1,6- bisphosphate. This compound will be divided and give DHDAP and glyceraldehyde -3- phosphate. The last compound will be the one used to give energy while the DHAP has to be transformed into glyceraldehyde -3- bisphosphate.
<u>Second step:</u>
In this step the glyceraldehyde -3- bisphosphate is transformed into pyruvate. In the process of the making of pyruvate 2 molecules of ATP are made from ADP and one molecule of NADH is made from NAD.
With the presence of O₂ the NADH can pass its electrons into the electron transport chain, regenerating the NAD in order to be used again in glycolysis. Also the pyruvate can be oxidized to carbon dioxide (CO₂) in cellular respiration, making molecules of ATP.
