A human pancreatic cell obtains O2 and necessary molecules such as glucose, as amino acids, and Cholesterol from its environment
MatroZZZ [7]

Answer:

Cellular membranes or plasma membranes has many functions. Some of these include regulation of cellular transport, and responding to cellular signals or hormones.

<h2>Cellular Transport</h2>

The plasma membrane is made up of the <u>phospholipid bilayer with embedded transmembrane proteins</u>. This makes the cell membrane <u>semi-permeable</u>. Movements of substances depend on the composition of the molecules e.g. glucose and amino acids, as needed by the pancreatic cells. These are larger and uncharged molecules and can't pass freely through the membrane so they utilize the transmembrane proteins via attaching to carrier proteins. This is called <em>passive transport</em>. On the other hand, in <em>active transport</em>, <u>ATP is used</u> to transfer molecules, like Hydrogen, from a low to high electrochemical gradient.

Other kinds of cellular transport are:

  • Osmosis and diffusion
  • Endocytosis
  • Exocytosis

<h2>Cellular Signalling</h2>

The cell membrane is able to signal other neighboring cells by utilizing complex proteins. These proteins may take form as receptors or markers.

<h3>Membrane Receptors</h3>

They act as receivers of extracellular signals and spark intracellular processes. These receive signals from hormones, growth factors, etc.

<h3> Membrane Markers </h3>

These allow the cells to identify each other and respond if this cell is needs further development as in organ development, or a foreign body to the system.

Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.<span> 
Two types: Anaerobic and aerobic respiration

Which statement correctly describes one way that the properties of water affect heat and temperature? Water retains more heat th
Sphinxa [80]
I believe the correct statement is that Water absorbs heat when it changes to vapor, helping to keep animals cool through perspiration. Water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to gas at constant temperature. In humans and other organisms, the evaporation of sweat, which is 90% water, cools the body to maintain a steady temperature.
