Step by step
Solved in 3 steps
- When P700 absorbs a photon, it releases an energized electron, which is immediately replaced by an electron provided by _____________.Many pelagic Bacteria can use light energy but arenot considered “phototrophs” in the same sense ascyanobacteria or purple bacteria. Explain.Yeast is a facultative anaerobe. This means that alcohol fermentation takes place only if: the temperature is close to 37°C the atmosphere does not contain oxygen sugar is provided to the cells light is provided to the cells
- Which statement about thylakoids in eukaryotes is not correct? a. Thylakoids are assembled into stacks. b. Thylakoids exist as a maze of folded membranes. c. The space surrounding thylakoids is called stroma. d. Thylakoids contain chlorophyll.What is the action spectrum? Question 15 options: a graph plotting a pigment's light absorption vs. wavelength a profile of the relative effectiveness of different wavelengths in driving photosynthesis the wavelengths of the electromagnetic spectrum that are visible lightPhotosynthesis can only be powered by sunlight. true or false explain in 3-4 sentences
- Why do the reaction centers have different pigments rather than only the chlorophyls? quantitatively increasing the absorption photons narrowing coverage of the visible spectrum light increasing coverage of the visible spectrum light arranging light-harvesting complexe compensating for the high density of chlorophyllA microbe lives solely on acetate. It has an Electron Transport Chain driven by oxygen that has two hydrogen pumps and both NADH and FADH deliver their hydrogens (and electrons) to the first pump hence each generates 2 ATP. How many ATP are generated per acetate molecule?Some prokaryotes are Chemoheterotrophs. Where do these organisms get their energy from? Group of answer choices From Light From Themselves From Inorganic Chemicals From Organic sources
- How many human eukaryotic cells does it take in a single second to use exactly one nanojoule (1 × 10−9 J) of energy if each cell uses 2.00 × 10−17 joules every second? Answer: __________ × 107 cellsYou have discovered a cyanobacteria with only photosystem I. The bacteria is unable to fix CO2. Explain thoroughly how you think this microorganisms makes ATP and reducing powerTrue/False: One organelle found in many photoautotrophs but not heterotrophs is the nucleus.
