Q. 7.77 - An Introduction to General, Organic, and Biological Chemistry

Question

a. During cellular respiration, aqueous $C_6{H}_{12}{O}_6$ (glucose) in the cells undergoes a reaction with oxygen gas to form gaseous carbon dioxide and liquid water. Write and balance the chemical equation for reaction of glucose in the human body.

b. In plants, carbon dioxide gas and liquid water are converted to aqueous glucose $C_6{H}_{12}{O}_6$and oxygen gas. Write and balance the chemical equation for production of glucose in plants.

Step-by-Step Solution

Answer

(a)  The balance the chemical equation for reaction of glucose in the human body is: ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{aq}\right) + 6{\mathrm{O}}_2\left(\mathrm{g}\right)\to 6{\mathrm{CO}}_2\left(\mathrm{g}\right)+ 6{\mathrm{H}}_2\mathrm{O}\left)\right(\mathrm{l})$

(b) The balance chemical equation for production of glucose in plants is:$6{\mathrm{CO}}_2( \mathrm{g} ) + 6{\mathrm{H}}_2\mathrm{O}( \mathrm{l} ) \to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6 (\mathrm{a} \mathrm{q}) + 6{\mathrm{O}}_2( \mathrm{g} )$

Part (a) Step 1: Given Information

We need to write a balance the chemical equation for reaction of glucose in the human body. 

Part (a) Step 2: Explanation

The balanced chemical equation of glucose with oxygen reaction in human body is:${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{aq}\right) + 6 {\mathrm{O}}_2\left(\mathrm{g}\right)\to 6 {\mathrm{CO}}_2\left(\mathrm{g}\right)+ 6 {\mathrm{H}}_2\mathrm{O}\left)\right(\mathrm{l})$

Since the Breakdown of glucose is a chemical reaction then $2870$kilojoules of energy are released for each mole of glucose that's metabolized .

Part (b) Step 1: Given Information

We need to Write and balance the chemical equation for production of glucose in plants. 

Part (b) Step 2: Explanation

The balance chemical equation for production of glucose in plants is: $6{\mathrm{CO}}_2( \mathrm{g} ) + 6{\mathrm{H}}_2\mathrm{O}( \mathrm{l} ) \to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6 (\mathrm{a} \mathrm{q}) + 6{\mathrm{O}}_2( \mathrm{g} )$Generally, photosynthesis Utilizes light Vitality to change over carbon dioxide into a starch.
