What structure on the human body is comparable to the alula?

1 answer:

7 0

The alula is a small structure that is found on birds. It is located at the joint between the hand wing and the arm wings of birds and it is the freely moving, first digit of a bird's wing. It is normally used by birds in slow flight. In humans, the structure that is comparable to the alula is the thumb.

Proteins are one of four classes of biological macromolecules. Which of the following statements regarding proteins is NOT true?

dangina [55]

Answer:

Statement 'C' is incorrect

Explanation:

Enzymes (which are a form of proteins) have a function of regulating the rate of biochemical reactions (they're biological catalysts, meaning they speed up reactions) ₋ in this instance, the statement would be correct.

However, this is not the only, or as the statement puts 'one specific function' of an protein. For example, haemoglobin (a protein) contains haem groups that bind to oxygen. In this instance, a protein's function has nothing to do with 'biochemical reactions'.

Hope that helps! x

The general function of an enzyme in the body is to ________. The general function of an enzyme in the body is to ________. elim

bixtya [17]

Answer:

catalyze chemical reactions

Explanation:

An enzyme is a proteinous substance that acts as biological catalysts and increases the rate of biochemical reactions in the body. Enzymes are specific in nature which is as a result of the structure/shape of its building block (amino acid).

Enzymes speedens the rate of a chemical reaction in living systems, which would normally not occur or occur at a much slower rate, without the presence of an enzyme. Enzymes acts on the reactants called Substrates by binding to them to form products but they are not used up in the reaction. Hence, enzymes are not reactants.

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it n

Paladinen [302]

Answer:

The correct answer is increasing the rate of cellular respiration in mitochondria.

Explanation:

In mammals like humans, the infection causes a rise or hike in the body temperature of an individual up to 2 - 3 degrees Celsius. Infection results in thermoregulation strategies control by the hypothalamus, of the host by immune system transmitted integration signals, hormonal and neuron lead and increase in metabolic reactions by the increase the rate of the cellular respiration takes place in the mitochondria and that elevate body temperature. Mitochondria releases energy in the form of ATP that helps in body temperature as it is an exothermic reaction.

The correct answer is increasing the rate of cellular respiration in mitochondria.
