What are the differences between enantiomers, diastereomers, and identical molecules in terms of their stereochemistry?
Enantiomers are mirror images of each other and have opposite configurations at all chiral centers. Diastereomers are stereoisomers that are not mirror images and have different configurations at some, but not all, chiral centers. Identical molecules have the same configuration at all chiral centers and are the same molecule.
How do enzymes get a reaction started?
My Biology teacher said "They speed up the rate at which all parts react"
What is meant by the enzyme specificity?
Enzymes work on one substrate specifically. This is why there is millions of different types of enzymes to interact with all the molecules they need to metabolically and chemically react with.
Do all enzymes have the same shape as their substrates?
Yes.
What isomers that are mirror images of each other?
Chiral molecules have mirror-image isomers
Are enzymes and proteins the same thing?
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.
Why are enzymes used in cellular respiration identical in all species?
The same genetic code produces those enzymes
What do all metals have in common when they react?
they have the elements and they are in the same substances
Denatured enzymes are the same as?
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.
Why are all enzymes catalysts but not all catalysts are enzymes?
but all catalysts aren't enzymes...
Are all possible enzymes present at the same time at the cell?
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.
What is difference between epimers and enantiomers?
Epimers are diastereoisomers that differ in the configuration at one stereocenter, while enantiomers are mirror images of each other with opposite stereochemistry at all stereocenters. Epimers have different physical and chemical properties, while enantiomers have identical physical and chemical properties except for their interaction with plane-polarized light.
