<span>Ohm's law deals with the relation between voltage and current in an ideal conductor. It states that: Potential difference across a conductor is proportional to the current that pass through it. It is expressed as V=IR. Therefore, the correct answer would be option 1. The current will increase as well since there is an increase in the voltage.</span>

How can insulin deficiency lead to an increase in blood glucose concentration?
MakcuM [25]

When insulin is deficient , GLUT4 transporters are not inserted into the cell membranes , glucose is not transported into the cells and the blood glucose concentration increases.

Insulin deficiency provides more amino acid and glycerol substrates for glucose synthesis  ie increased gluconeogenesis .

With a deficiency of insulin, there is both increased hepatic glucose production through increased glycogenolysis and gluconeogenesis as well as decreased glucose use. The result is hyperglycemia.

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative
Anon25 [30]

Answer:

\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

10^ {difference \ in \ pH}

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

10^5=100,000

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>

Consider a cell that requires much more ribose5‑phosphate than NADPH. The cell needs ribose 5‑phosphate but has a relatively hig
Sergio039 [100]

Answer:

The fate of glucose-6-phosphate,glycolytic intermediates and pentose phosphate pathways are described below

Explanation:

Fate of Glucose -6-phosphate

Glucose-6-phosphate undergo dephosphorylation to form glucose when there is an increase demand of glucose in the body.

Glucose-6-phosphate enters into pentose phosphate pathway to synthesize ribose-5-phosphate which is used during denovo pathway of purine nucleotide biosynthesis.

Fate of glycolytic intermediates

Glyceraldehyde-3-phosphate is an important intermediate of glycolysis.The glyceraldehyde-3-phosphate act as a precursor during lipogenesis that deals with the biosynthesis of triacylglycerol.

Fate of pentose phosphate pathway intermediates

Ribose-5-phosphate and NADPH are the important intermediates of pentone phosphate pathway.

 Ribose-5-phosphate act as a substrate molecule during the denovo biosynthesis pathway of purine nucleotides.

NADPH act as a reducing agent during fatty acid biosynthesis process.
