Question

also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. this oxygen is identical to the oxygen gas given off during photosynthesis.

1. (circle one) oxygen is a product or reactant of respiration

(in other words, is it needed or released?)
reflection question: explain the relationship between photosynthesis and cellular respiration. be sure to include the main purpose of both and where they occur inside the cell.
humans and plants
humans need plants. all animals do. humanitys relationship with plants has actually made it possible for us to have a civilization. before we had cities, humans went around in little packs and were hunter - gatherers. we ate rats, birds, berries, and whatever food we could find. it wasnt very efficient. one day someone had the bright idea to plant the plants we like to eat. when humans did that, they were able to stay in one place full time. then came the cities and a huge system of agriculture to support millions of people.
big time farming
as time has passed, we have taken farming to new levels. we have manipulated species to create big apples and large ears of corn. the plants would never have done it in the wild. it took man to change the plants. we are also moving toward the genetic alteration of plants. were trying to make plants that are resistant to disease and bugs. these stronger plants will allow our crops to give us more food from the same amount of space.

Explanation:

Photosynthesis is a process where plants use sunlight, carbon dioxide ($CO_2$), and water ($H_2O$) to produce glucose ($C_6H_{12}O_6$) and oxygen ($O_2$). The main purpose is to create food (glucose) and release oxygen. It occurs in the chloroplast. The reaction is \(6CO_2 + 6H_2O+sunlight
ightarrow C_6H_{12}O_6 + 6O_2\).

Cellular respiration is a process where cells (in mitochondria) break down glucose ($C_6H_{12}O_6$) and oxygen ($O_2$) to produce carbon dioxide ($CO_2$), water ($H_2O$), and energy (ATP). The main purpose is to release energy for the cell's activities. The reaction is \(C_6H_{12}O_6 + 6O_2
ightarrow 6H_2O + 6CO_2+energy\).

They are related as the products of photosynthesis (glucose and \(O_2\)) are the reactants for cellular respiration, and the products of cellular respiration ($CO_2$ and \(H_2O\)) are the reactants for photosynthesis.

Answer:

Photosynthesis: purpose - create food (glucose) and release oxygen; location - chloroplast; reaction \(6CO_2 + 6H_2O+sunlight
ightarrow C_6H_{12}O_6 + 6O_2\).

Cellular respiration: purpose - release energy; location - mitochondria; reaction \(C_6H_{12}O_6 + 6O_2
ightarrow 6H_2O + 6CO_2+energy\).

Relationship: Products of photosynthesis (glucose, \(O_2\)) are reactants for cellular respiration. Products of cellular respiration ($CO_2$, \(H_2O\)) are reactants for photosynthesis.
