The Effect of Sodium Bicarbonate Concentration on the Net Rate of Photosynthesis

Words: 495 Pages: 2 14253

During photosynthesis in plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds such as glucose (Lambers & Bassham, 2018). The equation for photosynthesis is: 6CO? + 6H?O + light energy = C?H??O? + 6O?. Without the presence of any one of the reactants, autotrophs such as plants cannot undergo photosynthesis and synthesize food and nutrients. In plants, the primary site of photosynthesis is within the leaves. The central leaf […]

Photosynthesis Vs. Cellular Respiration the Major Processess in a Global Balance

Words: 1454 Pages: 5 6582

There are two key processes that occur in nature to obtain energy, they are photosynthesis and cellular respiration. The derivative of the word photosynthesis is the process in which energy of sunlight is converted by plants to store chemical energy in carbohydrate bonds.

Degradation of Glycogen and Necrotic Cell Death

Words: 662 Pages: 2 3546

PYGL (glycogen phosphorylase) catalyzes degradation of glycogen and therefore allows it to be used as an energy source. The researchers were unable to obtain PYGL antibodies to further study the RIP3/PYGL interaction in necrosis. However, the interaction was induced by TNF but not zVAD. They incubated flag RIP3 missing glutathione S-transferase, which did not enhance PYGL activity and could only determine that RIP3 activates PYGL. They measured PYGL activity in N cells, RIP1 knockdown and RIP3 knockdown without and without […]

Photosynthesis in Living Leaves

Words: 1061 Pages: 4 4534

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 […]
