Explanation: Invertebrate do not have a spine.
The correct answer is this: ALL CELLS ARE PRODUCED FROM EXISTING CELLS.
Rudolf Virchows was a doctor and scientist of German origin. He was the first scientist to apply cell theory to mechanism of diseases in humans, this aspect of medicine is called pathological processes. Through his research, he discovered that new cells are always produced from existing cells.
Yes it does follow that ab has determinant 0
As a result of its involvement in a reaction, an enzyme is unchanged.
Enzymes are catalysts that speed up chemical reactions that occur within the biological systems (they increase the reaction rate by lowering its activation energy). Enzymes react with substrate that binds to them (key-lock mechanism) and convert the substrate into the product. Most of enzymes are proteins by their structure but a few are catalytic RNA molecules-ribosymes.
Enzyme activity can be affected by other molecules (activators and repressors), pH, temperature etc.
