Proteins may be classified according to their three-dimensional shapes. Determine whether the following examples and description
m_a_m_a [10]

Answer:

-often function as enzymes or transport proteins  ⇒ globular proteins

-peptide chains arranged in long strands, or fibers  ⇒ fibrous proteins

-peptide chains highly folded into spherical shapes  ⇒ globular proteins

-keratins  ⇒ fibrous proteins

-hemoglobin  ⇒ globular proteins

-water-soluble  ⇒ globular proteins

-collagens  ⇒ fibrous proteins

-insoluble in water  ⇒ fibrous proteins

-generally function in structure and support ⇒ fibrous proteins

Explanation:

<u>Fibrous proteins </u>are composed by large polypeptide chains which interact each other and form large structures. They have water insoluble and have structural and protection functions- they are components of cells and tissues. Examples are: collagen, fibronectin, keratin, elastin, actin.

<u>Globular proteins</u> have a spherical compact structure in which hydrophobic aminoacids are buried inside the structure and hydrophilic aminoacids (which can interact with water molecules) are exposed to the exterior medium. For this, they are water soluble. They have often transport and catalytic functions. For example: hemoglobin, mioglobin, albumin, enzymes in general.

aniked [119]

Answer:

He can deduce that The pO2 of her cells is less than or equal to 200 mmHg.

Explanation:

Partial pressure of oxygen(pO2) measures the amount of gaseous oxygen  dissolved in the blood. It purposes to measure the effectiveness of the lungs in pulling oxygen from the atmosphere to the lungs.

In the incubator where the gases levels are carefully regulated, a pO2 of 200mmHg on the incubator deduces that the pO2 of her cells is equal or less than 200mmHg.

How do earthworms get their energy
Allushta [10]

worms get their energy through the biological process of cellular respiration where glucose from the food they eat is converted into ATP. This molecule is packed with potential energy, and is used by the cells within the worm to do work.

Hope this helps (:
