Homework Answers
photorespiration is the process by which the Rubisco fixes oxygen to RuBP,
RuBP + O2
3-phosphoglycerate+ 2 phosphoglycolate
3-phosphoglycerate is 3 carbon molecule and 2 phosphoglycolate is a 2 carbon molecule so the answer is
d. the products are a two-carbon molecule and a three-carbon molecule.

Ribulose-1-5-biphosphate carboxylase (Rubisco) "fixes" carbon dioxide into biomass in the vast majority of photosynthetic organisms on Earth. We can tell that it evolved before Earth was oxygenated because it is poorly suited to an oxygenated atmosphere. A) What is one property of Rubisco that demonstrates that it is so poorly suited to an oxygenated atmosphere? B) Why do organisms in the ocean use carbon concentration mechanisms when they use Rubisco?

Photosynthesis - what is meant by each round? Carbon fixation occurs in the stroma of the chloroplast in a process known as the Calvin Cycle. It occurs in three stages: Stage 1: Carbon Fixation, Stage 2: Reduction, and Stage 3: Regeneration of RuBP. In Stage 1, __ molecule(s) of CO2 are added to __ molecules of RuBP, which was regenerated from the previous cycle. This process is catalyzed by the enzyme Rubisco. The final product from each round of the...

The Calvin Benson cycle use the energy trapped in ATP and NADPH generated by the light reactions to build sugars from CO2. What below is FALSE regarding this sugar-building cycle? Select one: a. Initially RuBP is carboxylated by RuBisCo where atmospheric CO2 is captured and put into the cycle. b. ATP and NADPH generated by the light reactions are used to reduce 3PG to a more energetic/reduced G3P (some of which will be diverted off to build sugar!) c. More...

A hemoglobin molecule can carry one oxygen or one carbon monoxide molecule. Suppose that the two types of gases arrive at rates 1 and 2 and attach for an exponential amount of time with rates 3 and 4, respectively. Formulate a Markov chain model with state space {+, 0, −} where + denotes an attached oxygen molecule, − an attached carbon monoxide molecule, and 0 a free hemoglobin molecule and find the long-run fraction of time the hemoglobin molecule is...
