Which is a major by product of respiration? Choose the correct answer.
lana66690 [7]

Answer:

This question is incomplete as it lacks options, however, it can be answered. The answer is:

CARBON DIOXIDE (CO2)

Explanation:

Cellular respiration is the process by which glucose is broken down in an organism's cell to release energy. Although the process involves series of reactions, however, the general equation is as follows;

C6H12O6 + 6O2 ➡ 6CO2 + 6H2O + energy

Based on the above equation, the inputs are glucose and oxygen while the outputs are carbon dioxide and water. Carbon dioxide (CO2) is the major byproduct of the respiration process.

Two diseases resulting from hyperfunction of the pituitary gland are:
Snezhnost [94]
Gigantism and acromegaly are the two diseases resulting from hyper function of the pituitary gland. Gigantism and acromegaly are conditions that are nearly always due to a pituitary adenoma that is because of excessive secretion of a growth hormone called hypersomatotropism. <span>If GH hypersecretion begins in childhood, before closure of the epiphyses pituitary gigantism occurs. It is a rare condition where skeletal growth velocity and ultimate stature are increased, but little bony deformity occurs. However, soft-tissue swelling occurs, and the peripheral nerves are enlarged. Hypogonadotropic hypogonadism and deferred puberty is also normally present, resulting in a eunuchoid habitus. While Acromegaly occurs after the growth plate cartilage fuses in adulthood, it is the same disorder of IGF-I excess but in acromegaly, an unadorned disease that morbidity and mortality rates are high because its often diagnosed late, where the disease is associated with cardiovascular, cerebrovascular, and respiratory disorders and malignancies. </span>

Eukaryotic cells. Classify each statement according to whether it occurs in eukaryotic cells, prokaryotic cells, or both.
frutty [35]

Answer:

<u>Both</u>:

  • The start codon is often AUG

<u>Eukaryotic cell only:</u>

  • The larger subunit of the ribosome is 60s.
  • The ribosomes initially binds the 5' end of mRNA.

<u>Prokaryotic cell only</u>:

  • The ribosome is 70s
  • Translation occurs in the cytoplasm
  • There are multiple ribosome binding site

Explanation:

  • AUG is the common start codon for both eukaryotic as well prokaryotic cells. In eukaryotic cell, it codes for methionine . While in prokaryotic cell, it codes for formyl methionine.
  • In prokaryotic cell, ribosomes are found in cytoplasm, hence the translation occurs in cytoplasm.
  • Eukaryotic ribosome consists of two subunits; 40s and 60s(larger subunit)
  • Prokaryotic ribosomes have 70s ribososme, which consists of 50s and 20s subuints
  • in eukaryotic cell, 40s ribosome initially binds to the cap at the 5' end of mRNA.
  • Bacterial mRNA contain multiple ribosome binding sites.

How does the genotype of a bacterium determine its phenotype? Use the terms gene, mRNA, ribosome, and polypeptide in your answer
tensa zangetsu [6.8K]
Typically, the genotype is encoded in the DNA by the gene; this gene in the DNA will then undergo the process of transcription and the information in the gene will be transcripted into mRNA. The mRNA will then undergo the process of translation and the information in the mRNA will  be translated into a polypeptide chiefly by the action of ribosome. Thus, bacteria with different genotypes will have different protein which automatically means that they will have different phenotypes.

Which statement best describes the cell membrane?
vredina [299]

Answer:C). A phospholipid bilayer with proteins

Explanation: A cell membrane is a phospholipid bilayer with proteins embedded in it. The fatty acyl chains of the phospholipids are non polar and hydrophobic while the phosphate groups are polar and hydrophilic. The hydrophobic regions of the phospholipids interact with each by facing each other, forming a bilayer with a fluid interior. The polar head groups face outward interacting with the external environment of the cell. Proteins are embedded in this bilayer and they float in this sea of phospholipids. Proteins anchored to the membrane through interactions between the hydrophobic regions of the phospholipids and the amino acid side chains of the proteins. These lipids and proteins swim laterally in each face of the bilayer but movement from one face of the bilayer to another is restricted.
