Calvin Cycle

The Calvin Cycle is basically a part of photosynthesis where plants take in carbon dioxide and uses ATP and NADPH to make sugars from the CO2 and water for the plant to use or for animals to eat. It does not require light, and is interestingly called the “dark cycle” 1.The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. 2.The…

Research_ Oxygen and Carbon Dioxide

I walk into my first period class at 9:29 right before the 9:30 bell rings for class to begin. My science teacher, Mr. Sherman, has to make an announcement to the class. He says, “I am assigning a five paragraph essay due at the end of the week about photosynthesis and cellular respiration. ” I thought to myself, how am I going to write a five paragraph essay on photosynthesis and cellular respiration? But then again, all it takes is…

Photosynthesis and Cellular Respiration

1. Organisms that use photosynthesis to produce glucose are collectively called photoautotrophs; three specific examples of such organisms are Rhodospirillum rubrum, Chromatium okenii, and Chlorobium limicola (Sengbusch, 2003). 2. Obligate aerobes are organisms that exclusively utilize aerobic cellular respiration; examples of such organisms are Bacillus, Pseudomonas, and Nocardia (Schlegel, 2003). 3. Unlike in aerobic cellular fermentation, organisms that utilize fermentation in cases wherein oxygen is absent use pyruvate along with other compounds derived from acetyl-CoA as a replacement for oxygen…
