All of the following are properties used to classify elements as metals, nonmetals & metalloids EXCEPT -texture
-conductivity
-luster
-malleability

texture

Explanation:

Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.

- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.

- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't

- Metals are malleable i.e. can be beaten into sheets.

Texture is not a property used to classify metals and metalloids.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
