Chapter 8 - Photosynthesis

Chlorophyll

________ is a light- absorbing pigment that absorbs photons from the sun.

Photosystems

________ are found in the chloroplast's thylakoid membrane and are linked by an electron transport chain (ETC)

PSI

________ and PSII include distinct forms of chlorophyll that absorb the greatest amount of light energy at slightly different wavelengths (700 nm and 680 nm, respectively)

Elysia crispata

Because photosynthesis requires light energy, limiting the intensity of the light would reduce the quantity of photosynthesis performed by the chloroplasts as well as the amount of food accessible to ________ from those chloroplasts.

Photosynthesis

________ is separated into two major components: light- dependent processes and light- independent reactions (also known as the Calvin cycle)

Glycolysis

________ and fermentation can be performed by anaerobic organisms that do not have access to or require oxygen.

sea slug

The ________ may grow more reliant on alternative food sources.

Protons

________ and high- energy electrons are employed to power ATP and NADPH synthesis (which are sent to the light- independent reactions)

Photoautotrophs

________ are autotrophs that use light energy to power this activity.

oxygen gas

The light- dependent processes divide water using sunlight's energy, creating ________, protons, and high- energy electrons.

NADP+

The electron is converted to ________ coupled with a proton by the enzyme ________ reductase after passing through a sequence of carriers similar to that of the ETC.

Heterotrophs

________ are creatures that devour other species to obtain organic compounds.

Chloroplasts

________ have an exterior membrane that is filled with stroma, a liquid.

six carbon molecule glucose

The ________, coupled with two molecules of the electron transporter NAD+, enters glycolysis.

light independent reactions

The ________ take place in the stroma, while the light- dependent reactions take place in the thylakoid.

Energy

________ is released when these excited electrons pass through the chloroplast.

Aerobic organisms

________ that lack oxygen can also engage in glycolysis and fermentation.

NADP+

________ takes these electrons at the conclusion of the light- dependent processes, creating NADPH, which is a source of reducing power for the light- independent reactions.

oxygen gas

The atmosphere is filled with ________.

Photosynthesis

________ happens in chloroplasts of plants.

Oxygen gas

________ is emitted.
