Write a short summary of each of the three phases of the Calvin Cycle:
a. carbon fixation
b. reduction
c. regeneration of RuBP
Answer:
Calvin cycle can be described under three stages:
Carboxylation: It is the fixation of CO_{2}CO2 into a stable organic intermediate. In this, CO_{2}CO2 is utilised for the carboxylation of RuBP. This reaction is catalysed by the enzyme RuBisCO and it results in the formation of two molecules of 3-PGA (3-Phosphoglyceric acid).
Reduction: These reactions lead to the formation of glucose. The steps involve utilisation of two molecules of ATP for phosphorylation and two of NADPH for reduction, per molecule of CO_{2}CO2 fixed. The fixation of six molecules of CO_{2}CO2 and six turns of the cycle are required for the removal of one molecule of glucose from the pathway.
Regeneration: For the cycle to continue uninterrupted, regeneration of the CO_{2}CO2acceptor molecule is crucial. This step requires one ATP for phosphorylation to form RuBP. To make one molecule of glucose, six turns of the cycle are required. 18 ATP and 12 NADPH molecules are used to make a molecule of glucose. Hence, for every CO_{2}CO2molecule entering the Calvin cycle, three molecules of ATP and two molecules of NADPH are required.
Place each description in the correct category.

Read the excerpt from "The Gift of the Magi" by O. Henry. What is the tone of the opening passage?
One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies, Pennies saved one and two at a time by bulldozing the
grocer and the vegetable man and the butcher until one's cheeks burned with the silent imputation of parsimony that such close dealing
implied. Three times Della counted it. One dollar and eighty-seven cents. And the next day would be Christmas.
There was clearly nothing to do but flop down on the shabby little couch and howl. So Della did it. Which instigates the moral reflection that life
is made up of sobs, sniffles, and smiles, with sniffles predominating.
While the mistress of the home is gradually subsiding from the first stage to the second, take a look at the home. A furnished flat at $8 per week
It did not exactly beggar description, but it certainly had that word on the lookout for the mendicancy squad.
In the vestibule below was a letter-box into which no letter would go, and an electric button from which no mortal finger could coax a ring. Also
appertaining thereunto was a card bearing the name "Mr. James Dillingham Young."
The "Dillingham" had been flung to the breeze during a former period of prosperity when its possessor was being paid $30 per week. Now, when
the income was shrunk to $20, though, they were thinking seriously of contracting to a modest and unassuming D. But whenever Mr. James
Dillingham Young came home and reached his flat above he was called "Jim" and greatly hugged by Mrs. James Dillingham Young, already
introduced to you as Della. Which is all very good.
OA dissatisfied
OB
humorous
OC sarcastic
OD. unhappy
Answer:
A. Dissatisfied
Explanation:
In the beginning of the excerpt, there are many uses of simple and concise sentence structures and a sense of discontent, such as "That was all".
Also, O. Henry includes harsh connotative word choice to effectively describe the apparent disatisfaction of the speaker, exaggerating the situation of how difficult it was to scrape up enough money, using words like "bulldozing" and "silent imputation of parimony". Using such words builds emphasis and importance of what lengths the speaker must endure in order to collect money.
When describing the "furnished flat", it's described as that "it did not exactly beggar description, but it certainly had that word on the lookout for the mendicancy squad". Depicting the flat in such a way evokes a disappointed tone towards how the speaker feels about the flat.
