according to lock and key model enzymes have specific geometrical shapes but due to more acceptance of induced fit model enzymes are flexible structures that change their shape according to their substrate.
No, not all possible enzymes are present in a cell at the same time. Each cell contains specific enzymes required for its metabolic processes, and the presence of enzymes is regulated by factors such as gene expression, cellular signaling, and environmental conditions. Enzyme production is tightly controlled to match the cell's metabolic needs.
No, nucleic acids are not enzymes. Nucleic acids are made up of nucleotides where as enzymes are proteins, but all proteins are not enzymes.
Enzymes are a form of a protein.
Enzymes are proteins but not all proteins are enzymes.
No, cells and enzymes are not the same thing. Cells are the basic unit of life and are made up of various organelles, while enzymes are proteins that act as biological catalysts to speed up chemical reactions within cells. Enzymes are a component of cells but are not the same as cells themselves.
Yes.
Enzymes are a type of protein that act as biological catalysts to speed up chemical reactions in living organisms. So, while all enzymes are proteins, not all proteins are enzymes.
The same genetic code produces those enzymes
Denatured enzymes are enzymes whose structure has been altered, leading to loss of their original function. They lose their ability to catalyze reactions efficiently or at all due to changes in their shape or folding. This can be caused by factors such as temperature, pH, or exposure to chemicals.
but all catalysts aren't enzymes...
No, not all possible enzymes are present in a cell at the same time. Each cell contains specific enzymes required for its metabolic processes, and the presence of enzymes is regulated by factors such as gene expression, cellular signaling, and environmental conditions. Enzyme production is tightly controlled to match the cell's metabolic needs.
no, enzymes are very specific with respect to stereo-chemistry and usually is active only to one enantiomer
Competition among various enzymes for same substrate
no
All cells do not contains the same types enzymes.
False. While some enzymes may function optimally at a pH of 7.4, not all enzymes have the same optimal pH. Enzymes can have a range of pH values at which they function best, depending on their specific structure and function.
No, nucleic acids are not enzymes. Nucleic acids are made up of nucleotides where as enzymes are proteins, but all proteins are not enzymes.
