1. Explain how an enzyme works, and how a coenzyme or cofactors may be involved in an enzymatic reaction.
An enzyme is a type of protein that is produced by living organism, that also speeds up a chemical reaction without actually being involved in the reaction itself. Reactions occur under mild conditions; enzymes also control the metabolism, by taking out nonspecific side reactions. Enzymes catalyze each step of the chemical reactions in a metabolic pathway. In order for this to happen, all enzymes are specified to a particular substrate, or a particular reactant. Only the active site of the enzyme associates directly with the substrate the majority of the time. The active site is the part of the enzyme that is specified to a particular …show more content…
Chloroplast is membrane bound organelle inside plant cells. chloroplast like many other organelles has a specific job. Chloroplast absorbs sunlight and uses it with water and carbon dioxide gas to produce food for the plant. chloroplasts also have the pigment chlorophyll, which absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, causing the plant to look green. Chloroplasts also contain flattened sacs known as thylakoids. Thylakoids are small compartments located in plant cells that help the plant absorb sunlight so photosynthesis can occur. These thylakoids contain a substance called chlorophyll. The chlorophyll absorbs the solar energy that drives the process of photosynthesis. Plants have two types of chlorophyll that play very prominent roles in photosynthesis: chlorophyll a and chlorophyll b. Chlorophyll a and chlorophyll b both absorb violet, blue, and red light better than the light of other colors. Most pigments only absorb some certain levels of wavelengths and they either reflect or transmit the other levels of wavelengths that they cannot absorb. plants do not use green light, instead plants reflect green light, Therefore, we see plants as having a green color.
