Chlamydomonas cells exposed to high light grow faster than cells grown under lower light. Why is that? A. Under high light, increased levels of G3P in the stromal of the chloroplast increase starch synthesis. B. Under high light, increased photosystem II activity leads to increased O2 levels which support higher rates of respiration. C. Under high light, high levels of cytosolic G3P support higher rates of cellular respiration and biosynthesis. D. Under high light, extra ATP can be exported from the mitochondria to support higher rates of glycolysis.
Give typed full explanation Consider the following equation: Nt = N0ert 1. What type of growth is modelled by this equation?
Chlorella is a photosynthetic alga that is related to Chlamydomonas. However, unlike Chlamydomonas, Chlorella is exclusively autotrophic. In what ways are these two species biochemically different? A. Chlorella can generate more G3P in the light than Chlamydomonas can B. Only Chlamydomonas can respire in the dark as well as the light. C. Only Chlamydomonas can gain carbon in the dark. D. Only Chlamydomonas can metabolize glucose.

What makes chlorophyll a different from chlorophyll b? Chlorophyll a has both porphyrin ring and phytol side chain. Chlorophyll b only has a porphyrin ring but not a phytol side chain. The phytol side chain of chlorophyll a is hydrophobic while the phytol side chain of chlorophyll b is hydrophilic. Chlorophyll a has a methyl group in its porphyrin ring.Chlorophyll b has an aldehyde functional group in its porphyrin ring. Chlorophyll a has an aldehyde group in its porphyrin ring. Chlorophyll b has a methyl functional group in its porphyrin ring.

Kindly refer to the image and answer the question 4. Explain the mechanism of action of the adenyl cyclic system using aschematic diagram.
If algae are exposed to 14CO2 for a brief period while illuminated, the labeled carbon is initially found almost entirely in the carboxyl group of 3-phosphoglycerate. However, if illumination is continued after the label pulse, other carbon atoms become labeled. Explain.
Which growth condition shown above has the largest doubling time? How would you explain the observed growth data based on information about metabolism and oxygen requirements? Definitely take into consideration the relative growth of all three growth conditions. Surprisingly, cultures grown in anerobic conditions are non-motile, whereas cultures grown in normal O2 saturation have several peritrichous flagella and swim motility. Explain briefly the mechanism of flagellar motility in terms of energy source for flagellar motility and why it may be lower in anaerobic conditions for L. monocytogenes.
