Cell Metabolism Wordle

Wordle: Untitled
In these chapters we learned about photosynthesis and cellular respiration, the cellular metabolism. We learned that photosynthesis is the conversion process that plants use to capture light or energy from the sun. heterotrophs obtain their material by living off other compounds produced by other organisms while autotrophs makes their own food. We also learned about the different parts or sites of photosynthesis. There is the chlorophyll which is where the color of the leaf comes from (green pigment), we learned about the mesophyll, which is the tissue in the inside of the leaf and we learned about the pores called the stomata which basically means the "mouth". the stomata is able to close or open depending on the circumstances. We also learned abotu the Calvin cycle which can be called the light cycle. We learned that light reactions convert the energy into ATP and NADPH which is a chemical energy. In cell communication, the process is able to be dissected into three stages: reception, transduction, and response. Signal molecules bind to receptor proteins wihch cause the protein to change shape. The signal molecule behaves like a ligand, which is a term for a small molecule that binds to a larger one in specific terms.
