The force that the soccer player kicked the ball with is still in effect, even though the player is not physically touching the ball. According to Newton's first law of motion, the object would stay in motion unless acted on by an unbalanced force. In this case, that force would be the friction of the ground.
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.
In Eukaryotes, the DNA replication can start at several sites or places in the DNA molecule or DNA strand. The only important factor for DNA replication to start is that it starts at replication fork.
The replication of DNA is semi-conservative in nature because each strand acts as a template for synthesizing a new complementary strand of the double helix.
The new DNA is made with the help of the enzyme DNA polymerase which requires a primer for starting the DNA synthesis.
Replication occurs only at specific regions of DNA known as origin of replication and these are short sequences of nucleotides which are recognized by the enzyme for the replication.
The special enzymes or proteins recognize the specific sites and then binds to them. After binding, the DNA is opened up forming the replication forks which are two Y- shaped structures.
