Answer:
When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).
The correct answer is...Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.

Answer:
Gigantopithecus could stand on its hind legs, and the known jaws of Gigantopithecus widen towards the rear and proposed that this widening occurred to allow for the housing of a trachea (the ‘windpipe’ that connects the lungs to the mouth opening) when the skull was placed directly in top of the head like a human and not carried forward like a great ape.
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum<span>, </span>golgi<span>apparatus, </span>lysosomes<span>, and peroxisomes</span>
