1) A fever is initiated by elevating the setpoint of the hypothalamic ‘thermostat’. a) What will happen to the metabolic rate once the setpoint has been raised? Please explain your answer briefly.

Answers

Answer 1
Answer:

Thermostat

Explanation:

  • The body tightly regulates the body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different
  • The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F)
  • The hypothalamus in the brain is the master switch that works as a thermostat to regulate the body’s core temperature
  • The nervous system constantly relays information about the body's temperature to the thermostat, which in turn activates different physical responses designed to cool or warm the body, depending on the circumstances
  • Responses may include: decreasing or increasing the flow of blood from the body's core, where it is warmed, to the surface, where it is cooled; slowing down or speeding up the rate at which the body turns food into energy (metabolic rate);inducing shivering, which generates heat through muscle contraction; and inducing sweating, which cools the body through evaporation
  • A fever occurs when the thermostat resets at a higher temperature, primarily in response to an infection
  • To reach the higher temperature, the body moves blood to the warmer interior, increases the metabolic rate, and induces shivering
  • The chills that often accompany a fever are caused by the movement of blood to the body's core, leaving the surface and extremities cold; Once the higher temperature is achieved, the shivering and chills stop

We are studying 3 strains of bacteria, with populations p1, p2, p3, in an environment with three food sources, A, B, C. In a day, an individual of bacteria 1 can each 3 units of food A, 2 units of food B, and 1 unit of food C. An individual of bacteria 2 can each 1 unit of food A, 4 units of food B, and 1 unit of food C. An individual of bacteria 3 can eat 2 units of food A and food B but does not eat food C.

Translate this sequence from mRNA to protein: AUG CAC UCG

Answers

Answer:

The result of the translation of the mRNA sequence AUG CAC UCG into protein is methionine, histidine and serine.

Explanation:

Messenger RNA (mRNA) is responsible for carrying the sequence of nitrogenous bases of its molecule to the ribosome to be translated into amino acids and synthesize proteins.

Three nucleotides of mRNA form triplets or codons that can encode:

  • The initiation of protein synthesis, with the AUG codon also coding for methionine.
  • Amino acids to be added to the peptide chain.
  • Stopping protein synthesis.

For the mRNA base sequence AUG CAC UCG, the amino acid sequence that corresponds to the synthesized peptide or protein is Met-His-Ser, i.e. methionine, histidine and serine.

Draw a circle and label the diagram below using the following words polymer and monomer

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of the diagram mentioned in the question. However, when the diagram is viewed, identify/label single unit (of a molecule) that is repeated as monomer. The entire stretch of the repeated units (monomers) should be labelled as polymer.

NOTE:

Monomers are simple units/building blocks of polymers. For example, glucose molecule (in a dextran) is a monomer and ethene (in polythene) is a monomer

Polymers are large molecules consisting of repeated units of monomers. Examples are polysaccharides (such as dextran) and polythene

What is the effect of an enzyme on the energy of a chemical reaction

Answers

Answer:

it increases speed of chemical reaction

Final answer:

Enzymes are proteins that speed up chemical reactions by lowering the activation energy, or the energy required for a reaction to take place. This makes reactions happen more efficiently and quickly.

Explanation:

An enzyme is a type of protein that accelerates, or catalyzes, chemical reactions. In relation to their effect on the energy of a chemical reaction, enzymes lower the activation energy. The activation energy is the energy threshold that must be met in order for a chemical reaction to occur. By decreasing this energy barrier, enzymes facilitate the process and make it proceed faster than it would without the enzyme.

For example, let's take the digestion of food in your body. The enzymes present in your digestive system speed up the chemical reactions that break down large food molecules into smaller units. This is because these enzymes reduce the activation energy required for these reactions, enabling the reactions to happen more efficiently and quickly.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.

Answers

Answer:

13,636 seconds = 227.3 minutes = 3.79 hours

Explanation:

The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).
