Photosynthetic physiology of Scenedesmus sp

Ranked from low (6.9) to high (9.1) pH from left to right
A malfunctioning colorimeter could cause inaccuracy light absorbency/ pH values

Similarly an indicator color guide is not 100% accurate and precise to compare to the color of the CO2 indicator resulting in slightly skewed data.
If temperature was the sole factor altered in the conditions of the algae beads for photosynthesis and cellular respiration, then room temperature will be most optimal for photosynthesis to occur
This is because certain enzymes will not work as efficiently in a colder environment and could denature in a hotter environment
We predict that the algae at room temperature will have the greatest rate of photosynthesis, then the 35 degree algae, and lastly the 45 degree algae
The glucose used in respiration to make ATP is formed during photosynthesis
The glucose turns back into CO2, which is used in photosynthesis
Water is broken down to form oxygen during photosynthesis, while during cellular respiration, oxygen is combined with hydrogen to form water

In the algae, photosynthesis occurs in chloroplast while cellular respiration occurs in the cytoplasm and mitochondria
The breakdown of food molecules occurs in the cytoplasm
In the mitochondria, the high energy is released

N2 - The effect of an increase in salinity on the physiology of the halotolerant chlorophyte Scenedesmus protuberans was studied in light-limited continuous cultures. It was observed that a gradual, as well as a steep increase in salinity resulted in lower biomass. However, the mechanisms by which this was achieved were different. In the culture that was exposed to a gradual salinity increase, respiration and the cellular protein content of the culture were initially unaffected. However, this culture was not able to maintain its cellular chlorophyll content and, consequently, gross and net photosynthesis decreased. The culture that was exposed to a steep salinity increase rapidly reacted by increasing its respiration and cellular protein content, which is ascribed to an induction of osmoregulation. This culture was able to maintain its gross photosynthesis rate. It is speculated that, in this species, a steep salinity increase induces a nearly immediate osmoregulatory response, allowing growth to continue. If the cells are exposed to a gradual salinity increase, induction of osmoregulation lags behind and, consequently, photosynthesis and growth rate will be affected.
