To review:
The coupling reactions involved in the emission of light in the fireflies by redrawing the given diagram.
Introduction:
The fireflies emit energy in the form of light and this phenomenon is known as bioluminescence. The light is emitted from an organ known as the firefly lantern, which is located in their abdomen. This is a form of mating signal through which the fireflies attract mates of the opposite sex.
During the generation of light by the luciferin in the firefly, an intermediate gets formed at the site of the luciferase enzyme. This complex consists of luciferin covalently bonded to adenosine monophosphate (AMP). This complex or intermediate further reacts with oxygen to give rise to oxidized form of luciferin, which ultimately emits light. These steps are shown in the figure as follows:

- The chemical reaction equation for the conversion of ethanol (C2H5OH) to acetic acid (CH3COOH) is: C2H5OH + O2 → CH3COOH + H2OIn a vinegar production industry, acetic acid is produced from ethanol during the growth of the bacterium Acetobacter aceti, whose cellular composition is CH1,8O0,5N0,2. The biomass yield from substrate is 0.14 g/g, while the product yield also from substrate is 0.92 g/g. Ammonia is used as a nitrogen source. Based on this information, answer: (a) What is the oxygen demand for acetic acid production in this crop?(b) What are the cooling requirements of a bioreactor containing 3000 L of ethanol (ρ = 789 kg/m³), to be completely converted into acetic acid?arrow_forwardWhat is the chemical species that is transferred through the light reactions? (Box A) What energy-rich compound is produced by the actions of the cytochrome complex? (Box B) What is the compound (Box C) used to donate electrons to the photosystems, and which gives rise to 2H+ and O2. What energy is used to energise the light reactions? (Box D) What is the product of the reaction that is occurring at NADP+ reductase?

Which colors of the visible light spectrum are absorbed best by chlorophyll a?arrow_forwardDescribe the purpose of the light dependent reaction and light independent reaction (carbon fixation reaction) in photosynthesis. In addition, explain how the products of the light dependent reaction are used in the light independent reaction (carbon fixation reaction)arrow_forwardWhich of the following statements is TRUE? Select one: a. The immediate product of the light energy absorbed by the P680 reaction center is used to produce NADPH. b. In cyclic photophosphorylation, the chlorophyll is reduced by electrons liberated from water molecules. c. The O2 gas produced during photosynthesis is derived from CO2. d. In noncyclic photophosphorylation, electrons from water are used directly for the reduction of P700. e. All of the statements are false.arrow_forward
- In 2010, a bew form of chlorophyll (chlorophyll f) was discovered in cyanobacteria assemblages of stromatolites growing in Shark Bay, Australia. Chlorophyll f has been isolated. and scientists are investigating the structure and function of this pigment. Based on your understanding of photosynthesis, how would you determine the wavelengths of light the pigment absorbs? How would you determine if this pigment plays a role in photosynthesis? (Hint: Think about the overall equation for photosynthesis.)arrow_forwardWhich of the following statements is FALSE? Group of answer choices: - Plastoquinone has a higher reduction potential than plastocyanin. - Water is the ultimate electron donor. - Proton gradient is created in the light phase of photosynthesis wherein the pH in the stroma is higher than in the lumen. - Photosystem II has chlorophylls in its reaction center that has maximum light absorption at 680 nm.arrow_forwardFor most plants, two distinct photosystems (Photosystem I and Photosystem II) work together in series during photosynthesis. These photosystems are complexes of proteins and pigment molecules. Statement 1: Photosystem I has an absorption maximum of 680 nm, whereas Photosystem II has an absorption maximum of 700 nm. Statement 2: The special pair of chlorophyll a molecules in the reaction center of photosystem I is designated as P700, whereas the special pair of chlorophyll a molecules in the reaction center of photosystem II is designated as P680. Statement 1 is true. Statement 2 is false. Statement 1 is false. Statement 2 is true. Both statements are true. Both statements are false.arrow_forward
- The equation for photosynthesis is 6CO2 + 6H2O + Sunlight --> C6H12O6 + 6O2. Explain the role of each of the products (left side of the arrow) and explain where the products (right side of the arrow) came from.arrow_forwardWhen discussing why the rate of photosynthesis did not increase at higher light intensities, the investigator mentioned the possibility that high light intensities could damage chlorophyll, which would result in a decrease in oxygen production. Which of the following accurately explains the role of chlorophyll in oxygen production during photosynthesis and why damage to chlorophyll would results in lower oxygen production? Select one or more: a. Chlorophyll participates in carbon fixation during the Calvin Cycle. During this process, oxygen molecules are formed. b. Chlorophyll captures energy from sunlight and releases high energy electrons that enter the electron transport chain in the Calvin Cycle. During this process, oxygen molecules are formed. c. Chlorophyll participates in carbon fixation during the light reactions. During this process, oxygen molecules are formed. d. Chlorophyll captures energy from sunlight and releases high energy electrons that enter the electron…arrow_forwardWhat is the significance that the combined absorption spectra of chlorophylls a and b roughly match the action spectrum of photosynthesis? Wouldphotosynthesis be more efficient if their individual absorption spectra coincided exactly?arrow_forward
