photosynthesis are essentially the same process in reverse. During photosynthesis CO2 and H2O are converted to glucose and oxygen‚ while cellular respiration uses glucose and oxygen which are converted to CO2 and H20. Plants utilize molecules of chlorophyll which harness energy from the sun. That energy is used to break the bonds in water molecules producing hydrogen and expelling oxygen as a byproduct. Atmospheric C02 is absorbed by the plant through its pores‚ and is then combined with the hydrogen

the glass molecules and prevented the droplet from falling when the glass was turned upside down. Water is polar. Its electrons are unevenly distributed among the molecule with two unshared electron pairs on the oxygen atom. The hydrogen atoms align themselves along one side of the oxygen atom‚ causing a slightly positive and slightly negative side. This causes a dipole to occur. Since glass is also polar‚ the water and the glass will be attracted to each other because of their positive and negative

activity that is poisonous to cells. Catalase speeds up the decomposition of hydrogen peroxide into harmless water and oxygen gas. The purpose of this lab was to determine whether an inhibitor affects the rate of activity for the enzyme catalase. Since catalase speeds up the production of oxygen gas‚ the rate of enzyme activity can be measured as the height of the column of oxygen gas bubbles produced in a test tube. If copper sulfate inhibits the action of catalase‚ then it will slow down the reaction

consisting of three oxygen atoms. It is an allotrope of oxygen. Ozone is formed when oxygen molecules after absorbing ultra violet photon then converts a single O2 into two atomic oxygen radicals. The atomic radicals then combine with separate O2 molecules to create two O3 molecules. The main function of the ozone layer is to absorb harmful ultraviolet radiation. These ozone molecules absorb UV light‚ following which ozone splits into a molecule of O2 and an oxygen atom. The oxygen atom then joins up

A variable portion of the oxygen produced from each leaf disc was floating to the surface instead of staying attached to the leaf disc it was produced from. If the oxygen produced via photosynthesis is lost in the sodium bicarbonate solution‚ it will not be contributing to the force pushing the leaf disc to the surface of the sodium bicarbonate solution

Nitrogen and oxygen make up 99% of the volume of clean‚ dry air. Nitrogen: 78%‚ Oxygen: 21% 4. Ozone is a form of oxygen that combines three oxygen atoms into each molecule. Its presence of the ozone layer in our atmosphere is crucial because it absorbs the potentially harmful ultraviolet radiation from the Sun. 1.7 3. Ozone

This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

the gas exchange between the lungs and the blood. O2 diffuses into the blood and CO2 diffuses into the lungs for exhalation. 6. What is the difference between inhalation and exhalation? a. Inhalation refers to the intake of air in order to supply oxygen to bodily tissues. Exhalation refers to the expulsion of carbon dioxide from the body. 7. How is the cardiovascular system
