If the translation does not occur or works badly, then the ribosomes can't create new proteins. If the body fails to make proteins, it stops working. That's because proteins are essential for the well being of your body, and not just in the sense that eating meat gives you protein. The ones created by ribosomes are much more important.
Answer:
The correct option is b
Explanation:
Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing). The phospholipid in the cell membrane acts as a selectively permeable barrier that regulates what goes in and out of the cell <u>thereby protecting the cell from some external molecules and ions</u>.
Answer:
Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient.
Explanation:
Ion channels are molecular machines that serve as principal integrating and regulatory devices for controlling cellular excitability. Different types of ion channels have been described: channels that respond to mechanical, electrical (voltage-dependent ion channels), or chemical stimuli (ligand-gated ion channels); ion channels that are controlled by phosphorylation/dephosphorylation mechanisms; and ion channels that are dependent on G proteins. Most ion channels are of the voltage-dependent type and consist mainly of sodium (Na+), potassium (K+), and calcium (Ca2+) channels. Drugs can affect ion channel function directly by binding to the channel protein and altering its function or indirectly through G proteins and other intermediates. Lidocaine is a good example of a drug that directly affects voltage-gated Na+ channels by blocking the channel and thus Na+ entry into the cell.
Thanks! Have a great day!
Plantae, because it is a kingdom of multicellular photosynthetic autotrophs that have cell walls containing cellulose
Answer:
The correct answer will be- codons and each codon specific for amino acids.
Explanation:
Deoxyribose nucleic acid is the genetic material of the organism which provides instructions for the organism. DNA is made up of nucleotide monomers which are composed of five-carbon sugar deoxyribose, a phosphate group and four types of nitrogenous bases (adenine, guanine, cytosine and thymine).
It is the arrangement of these nitrogenous bases which provide codes to the organism as it forms mRNA molecule through transcription. The sequence of the nitrogenous bases in mRNA is read by the ribosome during translation.
The ribosome reads the bases in triplets called "codon" which code for a specific amino acid. If the sequence of the base changes, therefore, the amino acid also changes. These amino acids bond to each other by peptide bond and form a protein molecule.
