Answer:
The correct answer is option c) "It is necessary to have a completely functioning pentose phosphate pathway for a tissue to synthesize ribose phosphates".
Explanation:
While the pentose phosphate pathway is the most common way at which a tissue synthesize ribose phosphate, it is false to affirm that it is necessary for ribose phosphate synthesis. Tissues have alternatives to the pentose phosphate pathway to synthesize ribose phosphate. For instance, the nucleotide salvage or the salvage pathway allows tissues to synthesize ribose phosphate from intermediates in the degradative pathway for nucleotides.
Answer
I added 4 and 5 as an attachment due to time constraint.
Explanation:
1. at a steady state ca2+ taken by vesicle = 40n/mol
enclosed volume of CSR = 5μ/mg
concentration of ca2+ in vesicle =
40*10⁻⁶/5x10⁻⁶
= 0.008
= 8x10⁻⁹mol/L
2. radius of circle =75nM
volume = 150nm
volume of vesicle = 4/3 x pi x r³
= 1.33 x 3.14 x (75x10⁻⁹)³
= 1.77 x 10⁻²¹
when we convert this we get
1.77x10⁻¹⁸L since 1m³ is equal to 100oL
surface area =4x3.14x(75x10⁻⁹)²
= 12.56x5.625⁻¹⁵
= 7.065x10⁻¹⁴m²
this is 7.065x10⁻¹⁰cm²
3. number of vesicle/CSR
= 5x10⁻⁶/1.77x10⁻¹⁸
= 2.824x10¹²
surface are = 2.824x10¹² x7.06x10⁻¹⁰
= 19.95x10²
Answer:more decrease in fish
Explanation:because that penguins source of food most of the time
We suppose the black fur is A and the white fur is a. The capital letter represents the dominant. Then the heterozygous black male is Aa and homozygous white female is aa. Then the offspring has two types, Aa and aa. The possibility of these two is equal and both are 50%.
