Chapter 10- Photosynthesis

PEP carboxylase

________ is common in mesophyll cells near the surface of leaves, while rubisco is found in bundle sheath cells that surround the vascular tissue in the interior of the leaf.

electron energy

When the ________ produces light, it is called fluorescence.

reaction sequence

The ________ resembles respiration, because it consumes oxygen and produces carbon dioxide.

Excite

________ an electron in a nearby pigment and induce resonance.

thylakoid membrane

In the chloroplast ________, 200- 300 chlorophyll molecules and accessory pigments are organized by associated proteins to form large complexes called photosystems.

Engelmann

________ concluded that they defined the action spectrum for photosynthesis- the wavelengths that drive the light- capturing reactions.

Plastoquinone

________ (PQ) is a quinone similar to ubiquinone in the ETC of cellular respiration.

Photosynthetic organisms

________ that oxidize water will generate oxygen (02) as a by- product, and thus perform oxygenic " (oxygen- producing) "photosynthesis.

Pheophytin

________ is identical to chlorophyll except that ________ lacks a magnesium atom in its head region.

synthesis of ATP

Since the ________ in chloroplasts is initiated by the energy from light, it is called photophosphorylation.

NADPH

Electrons from photosystem I are used to produce ________, which is a reducing agent similar in function to the NADH and FADH2 produced by the citric acid cycle.

Calvin

The reactions that reduce carbon dioxide and produce sugar came to be known as the ________ cycle.

surface of a leaf

The ________ is dotted with openings bordered by two distinctively shaped cells called guard cells.

thylakoids

The fluid- filled space between ________ and the inner membrane is the stroma.

Pigments

________ are molecules that absorb only certain wavelengths of light- other wavelengths are either reflected or transmitted.

chain of redox reactions

The electrons that pass from water to NADP+ move through a(n) ________ in a linear fashion, referred to as noncyclic electron flow.

small diffusible protein

When electrons reach the end of the cytochrome complex, they are passed to a(n) ________ called plastocyanin (PC)

photosystem II

In ________, the action often begins when a mobile accessory UCture called the light- harvesting complex transmits resonance energy to an antenna pigment inside the photosystem.

absorption spectrum

A(n) ________ measures how the wavelength of photons influences the amount of light absorbed by a pigment.

visible spectrum

Chlorophylls, designated chlorophyll αand chlorophyll b, absorb strongly in the blue and red regions of the ________.

Electromagnetic radiation

________ is characterized by its wavelength- the distance between two successive wave crests or troughs.

antenna pigments

When ________ absorb photons, the energy- but not the electron itselι is passed to a nearby pigment molecule, where another electron is excited in response.

Photosynthetic organisms

________ can not store the electromagnetic energy of light unless it is first converted into another form.

Pigments

________ appear colored because people see only the wavelengths that are not absorbed.
