Autotrophy is MOST ACCURATELY defined as
Select one:
a. the synthesis of organic matter from inorganic materialsusing energy from light or oxidation of reduced molecules orelements.
b. the breakdown of organic matter to yield energy.
c. recycling of cellular structures.
d. the light driven assimilation of CO2 into organicmatter.
A pot plant sits on a windowsill absorbing sunlight. How does aroot cell (which is in the dark) obtain its energy for cellularfunction, such as active transport across its membrane?
Select one:
a. Carbohydrates are made in the leaves via photosynthesis andmoved to the root
b. The root cell makes carbohydrates using the dark reaction(Calvin cycle) of photosynthesis
c. ATP is made within the leaves via photosynthesis and moved tothe root
d. The root cell utilises infrared light to photosynthesiseorganic carbon molecules
For the successful production of NADPH in photosynthesis, whatmust occur?
Select one:
a. Coenzyme Q is reduced and transfers electrons from complex Ito complex II.
b. The direct transfer of electrons from Photosystem II to theprotein plastocyanin.
c. The passing of protons through NADP+ synthase fromthe stroma to the thylakoid lumen.
d. A second input of light energy at Photosystem I to produceelectron donor molecules capable of reducing NADP+.
In the Calvin Cycle, the regeneration ofRibulose-1,5-biphosphate (RuBP) from 3-carbon compoundsrequires:
Select one:
a. Electrons from NADPH
b. Energy from ATP
c. Catalysation by rubisco
d. Oxidation of pyruvate
An anoxygenic photosynthetic bacteria is growing on ahydrothermal vent in the deep ocean. Which of the following isTRUE?
Select one:
a. It releases an oxygen molecule as a waste product
b. It uses hydrogen sulphide as the electron donor
c. It releases carbon dioxide as a waste product
d. It uses water from the surrounding ocean as the electrondonor
