14. Valuable molecules like glucose, amino acids, and vitamins are reabsorbed into the blood at which location in the nephron?
docker41 [41]

Answer: Option C) proximal convoluted tubule

Explanation:

The nephron has the proximal tubule where some water, amino acids and salts which are useful to the body are reabsorbed into the blood capillaries against concentration gradient by active transport.

Thus, the process of selective reabsorbtion takes place in the proximal convoluted tubule

A student's grade goes from a 95 to a 65 in 3 weeks. Calculate
steposvetlana [31]

-10grade/week

Explanation:

Given parameters:

Initial grade = 95grade

Final grade = 65grade

Time = 3weeks

Unknown parameter:

Rate of change of grade = ?

Solution:

Rate is defined as the change of a quantity with time.

 Rate of change of grade  = \frac{Final grade - Initial grade}{Time}

Rate of change of grade  = \frac{65 - 95}{3} = \frac{-30}{3}

Rate of change of grade = -10grade/week

The rate of change of the student's grade is -10grade/week. It implies that the grade of the student reduces by 10unit per week.

Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino a
vampirchik [111]

Answer:

a. True

Explanation:

Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).

What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plas
Yakvenalex [24]

Answer:

The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.

Explanation:

The Na/⁺K⁺ pump is an ATPase pump which is responsible for maintaining low Na⁺ and high K⁺ concentrations within the cytoplasm while maintaining high Na⁺ and low K⁺ concentrations in the extracellular fluid.

Since these two ions are moved against their concentration gradient, ATP hydrolysis is required to provide the energy for this process. This is done by moving in two K⁺ ions  inside while moving three Na⁺ ions outside the cell for every molecule of ATP hydrolysed to ADP and Pi.

If a competitive non-hydrolyzable analog of ATP is applied on the cytoplasmic side of a plasma membrane that contained a large concentration of the Na/⁺K⁺ pump, it will act by inhibiting the action of the Na/⁺K⁺ pump. This will result in an accumulation of Na⁺ ions inside the cell and lower than normal K⁺ ions concentration.
