Photosynthesis in Living Leaves

Words: 1061 Pages: 4 5758

Abstract The rate of photosynthesis can be measured by examining the amount of reactants and the buildup of products. Oxygen is a product of photosynthesis and is stored in the spongy mesophyll. This gives the organism the ability to float. In this experiment, oxygen is taken out of the spongy mesophyll. The leaves are then placed into the bicarbonate solution with soapy water. The spongy mesophyll fills with the solution, causing the leaves to sink. A light source was placed […]

Essay about Resistance to Stress

Words: 480 Pages: 2 4223

Caloric restriction extends longevity in yeast because the absence of Tor/Sch9 signaling causes a metabolic change that uses acetic acid, which is similar to the generation and use of ketone bodies, acetoacetic acid, and lower than that of glucose (Wei et al., 2009). High levels of acetic acid promotes apoptosis in yeast and is the primary factor promoting culture acidification, chronological aging, and apoptotic death (Burtner et al., 2009). Tor/Sch9 pathway blocks the utilization of acetate. Tor-Sch9 deficiency extends longevity […]
