The bright yellow blooms of daffodils are a wonderful sign that spring has arrived. The daffodil is virtually synonymous with spring. Though their botanic name is narcissus, daffodils are sometimes called jonquils, and in England, because of their long association with Lent, they're known as the "Lent Lily." Lore connecting the daffodil to not only a sign of winter's end but a lucky emblem of future prosperity is found throughout the world. In Wales, it's said if you spot the first daffodil of the season, your next 12 months will be filled with wealth, and Chinese legend has it that if a daffodil bulb is forced to bloom during the New Year, it will bring good luck to your home.

The ATPase Synthase Complex Q12.1: Why are 4 H needed for every ATP synthesized and exported by mitochondria, even though only 3

sergey [27]

Answer:

1 H is consumed in exchanging the synthesized ATP in mitochondria with ADP in cytosol by adenine nucleotide translocator (ANT).

Explanation:

The electrons from NADH and FADH2 are transported in electron transport chain through various complexes that act as electron transporter, to oxygen. In this process, the pumping of protons from mitochondrial matrix to intermembrane space causes a concentration gradient and hydrogen ions diffuses out of matrix space through ATP synthase causing the production of ATP.

3 H are enough to pass through ATP synthase for the phosphorylation of ADP to produce ATP. 1 H or 25% of energy yielded from electron transfer is required to exchange the matrix ATP with the ADP in intermembrane space by adenine nucleotide translocator (ANT). This process provides continuous supply of ADP to mitochodaria and ATP which is exported to cytosol is utilized by cell to perform various functions. There will be no ATP production in mitochondria without ADP. So 4 H are required for 1 ATP production.

1 H for importing ADP to mtichodaria + 3 H for phosphorylation of ADP to ATP

A plasmid 41 twists and 6 right handed writhes. What is the Lk for this plasmid?

OLEGan [10]

Answer: Lk for this plasmid = 47

Explanation:

The formula to compute Lk is given by :-

Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)

Given: A plasmid 41 twists and 6 right handed writhes.

i.e. Twist (Tw) = 41 , Writhe (Wr) = 6

Then, Topological Linking Number (Lk) for this plasmid : = 41+6

= 47

Hence, the Lk for this plasmid = 47
