Abstract and Intro for Photosynthesis Manuscript
Abstract
The process of photosynthesis can be summarized as the photoautotroph consumption of carbon compounds as food and release of oxygen compounds as waste. The methods to measure the rate of photosynthesis are various. One method utilizes CO2 sensors to measure photoautotrophs CO2 intake under various luminescent environments. An elementary method utilizes H2O and NaHCO3 (Sodium Bicarbonate) for submersion of deoxygenized photoautotroph specimens to measure the release rate of oxygen compounds. Through the submersion method we recorded the rate of oxygen diffusion into the environment by observing the time it takes photoautotrophic specimens to reach buoyancy. The results produced from 40 mL of H2O, 1%, 0.6% and 0.3% NaHCO3 were within 25 minutes of initial submersion. The plurality of submerged photoautotrophic specimens resulted in release rates greater than 10 minutes for initial and final buoyancies in the solutions.

Introduction
The production of organic compounds by photoautotrophs is known as photosynthesis. Oxygenic photoautotrophs require light, carbon dioxide, nitrogen and H2O to produce oxygen (Mauzerall,1972). Oxygenic photosynthesis can be measured with the formula CO2 + H2O ===>> CH2O + O2. (J. Whitmarsh and Govindjee ,1995). This process occurs inside the photoautotroph organisms cells, more specifically in the chloroplasts.
Chloroplasts are organelles located within specific leaf cells in which the photosynthetic process occurs. The chloroplast organelles are made up of an outer and inner envelope membrane. Like the outer membrane, a chloroplasts inner membrane is permeable to H2O, CO2 and O2 compounds. However, the inner membrane acts as a barrier, directing the flow of charged and organic molecules. Within the inner membrane of chloroplasts is an extensive membrane structure known as the thylakoid membrane (Photosynthetic membrane). The thylakoid membrane houses
