They have different sizes and shapes. An example would be a tomato and a grape. Tomatoes are red, grapes are purple/green. Grapes are small, tomatoes (most of them) are large. This must be because the cells that make the tomatoes differ from the one that makes the grapes. Hope this helped/made sense :)
Answer:
Enzymes are biocatalysts which increases the rate of the biochemical reaction by lowering the activation energy of the reaction.
It performs the catalysis in four steps:
- The substrate enters the active site of a specific enzyme. The specificity is determined by shape complementarity and non-covalent interactions such as hydrophobic interactions.
- These interactions bring some changes in the shape of the active site of the enzyme which results in the formation of the enzyme-substrate complex.
- The process of catalysis takes place by which the substrate is converted into the product. It includes the breaking or rearrangement of old bonds and formation of new bonds. It results in the formation of enzyme-product complex.
- The product has different properties as compared to the substrate due to which it gets released from the active site of the enzyme. The free enzyme is ready to initiate a new cycle.
Thus, the correct answer would be the formation of the enzyme-substrate complex.
Prokaryotes do not have a nucleus and membrane bound organelles. Eukaryotes have a nucleus and membrane bound organelles
Gravity is a force that can make things go down hill.
Answer:
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All-stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
