The rate of reaction was negative, meaning that the reaction that occurred was endergonic. It absorbed more energy than it released for the reaction to take place.
Inside the bio chambers, the amount of carbon dioxide was decreasing which in turn made the reaction a negative number.
According to the data, photosynthesis was occurring in the leaves.
When the amount of heat on the plant increases, the amount of production from the carbon dioxide decreased.
The spinach leaves are the autotrophs in this experiment. The chloroplast of the autotroph broke down water molecules and carbon dioxide from the air to produce glucose and oxygen molecules. The chloroplast did this by capturing light energy from the light. This process is known as photosynthesis.
- the more carbon dioxide there was for a reaction to occur, the faster photosynthesis would occur because there would be more energy for the enzymes to create glucose and oxygen faster.
if the light were too hot, the light energy from the lamp could possibly denature the enzymes and the rate of reaction would decrease. If the lamp were too cold, there wouldn’t be enough light energy for the enzymes to create bonds.
- if the pH level was too acidic or too basic, the enzyme could also be denatured and the rate of the chemical reaction would decrease.
Intensity of Light
- The closer the light is to the leaves, the faster of carbon dioxide levels would decrease because more light equals more energy. If the light were too hot, the enzymes could also be denatured.
Amount of Water-
The rate of production of oxygen and glucose is affected by the amount of water on the leaf. The more water there is, the faster photosynthesis would occur because there is more energy in the bonds that will provide the enzymes to create the product faster.
Photosynthesis and Respiration
1. The ‘’In the Dark’’ value rates were positive because the leaves had been placed in a respiration chamber that was deprived of light. For this the plants were unable to perform photosynthesis and released carbon dioxide instead of oxygen as a by-product. 2. The ‘’In Light’’ value rates were negative, because unlike the ‘’In the Dark’’ experiment the leaves had light. With the light the leaves were able to perform photosynthesis in the respiration chamber, decreasing rates of carbon dioxide flow.
3. Evidence that there was cellular respiration occurring in the leaves was that in the
‘’In the Dark’’ data there showed an incline. This interprets that
