In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best supports the claim that this species is better adapted to environmental changes than other photosynthetic species are?
a) The additional pigments allow the species to outcompete other species for the wavelengths of light commonly used in photosynthesis.
b) The increased pigment concentration better facilitates energy production within the cells of the species.
c) The pigment combination allows the organism to absorb heat as well as light, making better use of available energy.
d) The additional pigments allow the species containing them to harvest energy from wavelengths of light that the other photosynthetic species cannot use.
Which definition is INCORRECT?
A) O Photoexcitation: light absorption leads to raising an electron to a higher energy state.
C) O Photolysis: light absorption coupled to splitting a molecule.
D) O Photophosphorylation: a form of substrate level phosphorylation used for ATP formation
E) O Photosynthesis: is often photoexcitation and photolysis coupled with CO2 fixation and biosynthesis

- To identify the molecule that accepts CO2, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off CO2 or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. How would these experiments help identify the CO2 acceptor? Select one: a. The CO2 acceptor concentration would decrease when the CO2 is cut off, but increase when the light is cut off. b. The CO2 acceptor concentration would increase when the CO2 is cut off, but decrease when the light is cut off. c. The CO2 acceptor concentration would decrease when either the CO2 or light are cut off. d. The CO2 acceptor concentration would increase when either the CO2 or light are cut off.arrow_forwardWhy is nitrogen fixation so energetically costly?arrow_forwardPlease answer all questionsarrow_forward

Energy is transformed during the process into chemical energy in the form of sugars, such as carbohydrates. However, the energy available at top consumers is much less than that produced by autotrophs. Why is this so?arrow_forward
