J. C. Servaites, in Plant Physiol. (1985) 78:839–843, observed that Rubisco from tobacco leaves collected before dawn had a much lower specific activity than the enzyme collected at noon. This difference persisted despite extensive dialysis, gel filtration, or heat treatment. However, precipitation of the predawn enzyme by 50% (NH4)2SO4 restored the specific activity to the level of the noon-collected enzyme. Suggest an explanation.

- Why it is called four o'clock plant?arrow_forwardThe break down of sugar occurs in biological cells. It goes through multiple stages to produce energy that cells use. One series of reactions during this process is call the citrus acid cycle. Discuss how you could either speed up or slow down the degradation of glucose through the citrus acid cycle? (Hint: look at the citrus acid cycle and choose one step)arrow_forward(a)What are the two superfamilies of proteins in which amylase is categorized?

- Why CaCl2 is used in the plants?arrow_forwardWhat is a justification for a hypothesis stating that copper ion is the necessary cofactor in the catechol oxidase reaction? In other words, what evidence based on observation is there to support this claim? Hints: Citric Acid and EDTA bind to copper ions to inhibit cofactor ability. In the catechol oxidase reaction, benzoquinone is produced. What does benzoquinone do in fruits and plants? How does it preserve food? Does citric acid have this same effect?arrow_forwardWhat is the major activator (non-allosteric, direct-activator) of phosphorylase?

- What do the yeasts provide for the fermentation chambers?arrow_forwardIn class, we described how germinating plant seeds can convert fatty acids to carbohydrates using the glyoxylate cycle. Using this mechanism, you may expect that three palmitoyl-CoAs (16 carbon fatty acid-CoA) should be able to produce 8 glucose (6 carbon) molecules. This is because 16 * 3C = 48 carbons = 8 * 6C. But in reality, this is not the case. Why? How many palmitoyl-CoAs do you actually need to produce 8 glucose molecules?arrow_forwardAssume that the substrate cycle that exists as shown undergoes reciprocal regulation such that the production of B is upregulated by 50% and the production of A is downregulated by 50%. What will the next flux of B in this situation be?
