Document Summary
Photosynthesis: the process of converting the energy of sunlight into carbohydrates. Autotrophs: organisms that make all of their own food from ions and simple molecules: photosynthetic organisms. Heterotrophs: organisms that derive their food from other organisms. Light dependent reactions: electrons are transferred to nadp to form nadph, an electron carrier similar to nadh, atp is made, split h20 to produce o2. Light independent reactions: co2 is reduced to make sugars, light is not necessary, uses electrons and atp, the calvin cycle, photosynthesis occurs in the chloroplasts of green plants. Leaves contain millions of chloroplasts: chloroplasts (like mitochondria) Contain everything that is required for photosynthesis to occur: thylakoids. Vesicle like structures that are inside of the chloroplast. The space inside the thylakoid is its lumen. Stroma= the fluid filled space between the thylakoid and the inner membrane: chloroplast thylakoid membranes contain the pigment chlorophyll, chlorophyll absorbs blue and red light and reflects green light, light spectrum.
