Chapter 10 - Photosynthesis

photosynthesis mechanism

The ________ most likely evolved in a population of bacteria with infolded portions of the plasma membrane harboring clusters of such molecules.

Solar energy

________ is used in the light processes to convert NADP+ to NADPH by contributing a pair of electrons and an H+.

White automobiles

(________ are the coolest since their paint reflects all visible light wavelengths .)

Photosynthetic enzymes

________ and other molecules are clustered together in a biological membrane to efficiently carry out the required series of chemical reactions.

NADP1

Light absorbed by chlorophyll causes electrons and hydrogen ions to be transferred from water to an acceptor termed ________ (nicotinamide adenine dinucleotide phosphate), where they are temporarily stored.

Chloroplasts

________ are cellular organelles found in plants and other photosynthetic organisms.

Decomposers

________ are heterotrophs that devour the remnants of other species by ________ and feeding on organic litter such as dead organisms, excrement, and fallen leaves.

Photosynthesis

________ turns light energy into chemical energy in the form of food.

source of energy

Plants, in particular, are photoautotrophs, which are creatures that use light as a(n) ________ to create organic compounds.

Heterotrophs

________ are the consumers of the biosphere.

white light

When we shine ________ on a pigment, we see the hue that is most reflected or transmitted by the pigment.

Autotrophs

________ synthesize organic compounds from CO2 and other inorganic raw materials found in the environment.

light processes

The ________ also produce ATP by utilizing chemiosmosis to drive the addition of a phosphate group to ADP, a process known as photophosphorylation.

ultimate suppliers of organic molecules

Because autotrophs are the ________ for all nonautotrophic species, scientists refer to them as the biosphere's producers.

organic molecules

An organism obtains the ________ it needs for energy and carbon skeletons through one of two mechanisms: autotrophic nutrition or heterotrophic nutrition.

Chloroplasts

________ include specialized molecular complexes that transform light energy that has traveled 150 million kilometers from the sun to chemical energy that is stored in sugar and other organic molecules.
