What are the General steps in enzyme catalyzed reaction?
In an enzyme-catalyzed reaction, the general steps include: substrate binding to the active site of the enzyme, forming an enzyme-substrate complex. This complex undergoes a reaction, leading to the formation of products. Finally, the products are released from the enzyme, which remains unchanged and can continue catalyzing more reactions. The enzyme facilitates the reaction by lowering the activation energy required for the reaction to occur, increasing the reaction rate.
What are DNA strands separated by?
Assuming this is regarding DNA replication or transcription, the enzyme helicase separates the two strands.
What molecule will proofread the new DNA strands?
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.
What is a substrate in the context of enzyme reaction?
Enzyme-substrate specificity means that a substrate can fit into an enzyme similar to a key fitting into a lock. The active site of the enzyme is what determines its specificity. An enzyme can hence catalyze a reaction with a specific substrate, such as amylase catalyzing starch molecules. During these reactions, the substrate is held in a precise optimum position to create and break bonds, catalyzing the molecule.
Where is ATPase enzyme needed for muscle contraction located?
It is in the mitochodria and speeds up the formation of ATP by breaking down ATP into ADP + energy. Muscle cells have many more mitochrondia than other cells.
The enzyme pyruvate kinase is responsible for catalyzing the conversion of phosphoenolpyruvate into?
pyruvate
What enzyme adds base pairs in order to create the new strands in DNA replication?
DNA polymerase is the enzyme responsible for adding complementary nucleotides to the template strand during DNA replication. It creates the new strands by catalyzing the formation of phosphodiester bonds between the nucleotides.
What enzyme is responsible for catalyzing immediate energy system?
The enzyme responsible for catalyzing the immediate energy system is creatine kinase. This enzyme helps in the regeneration of adenosine triphosphate (ATP) from adenosine diphosphate (ADP) during high-intensity, short-duration activities like sprinting or weightlifting.
Enzyme that analyzes the formation of the sugar to phosphate bonds in DNA?
The enzyme that analyzes the formation of the sugar to phosphate bonds in DNA is DNA polymerase. DNA polymerase is responsible for catalyzing the formation of the phosphodiester bonds between deoxyribose sugars and phosphate groups in the backbone of the DNA molecule during DNA replication.
What type of biology do DNA ligase belong to?
DNA ligase belongs to the field of molecular biology, specifically enzyme biology. It plays a crucial role in the process of DNA replication and repair by catalyzing the formation of phosphodiester bonds between DNA strands.
Example of enzyme responsible for a synthesis of a substance?
DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It catalyzes the formation of phosphodiester bonds between nucleotides to create a complementary strand of DNA based on a template strand.
How is DNA made in your bodies?
DNA is made in the body through a process called DNA replication. This involves the separation of the two strands of DNA, followed by the synthesis of two new complementary strands using the existing strands as templates. The enzyme DNA polymerase plays a key role in catalyzing the formation of new DNA strands.
What enzyme cuts and seals DNA?
The enzyme that cuts DNA is called a restriction enzyme, while the enzyme that seals DNA is called DNA ligase. Restriction enzymes cut DNA at specific sequences, creating breaks in the DNA strands, while DNA ligase seals these breaks by catalyzing the formation of phosphodiester bonds between the DNA fragments.
What class of enzyme is DNA polymerase?
DNA polymerase is a catalyst, by catalyzing the synthesis of new DNA by adding nucleotides to a preexisting chain. There are several different DNA polymerases, but DNA polymerase I and DNA polymerase II play the major roles in DNA replication.
What is the role of DNA polymerese in DNA replecation?
DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It adds nucleotides to the growing DNA chain by catalyzing the formation of phosphodiester bonds between nucleotides. DNA polymerase also has proofreading capabilities to ensure accuracy in replication.
What type of biological molecule is an exonuclease?
An exonuclease is an enzyme that hydrolyzes nucleotides from the end of a nucleic acid chain. It is a type of protein, which is a biological macromolecule responsible for catalyzing biochemical reactions in living organisms.
What enzyme builds new DNA strands from existing strands during DNA replication?
DNA Polymerase III is responsible for adding new nucleotides to the strand being synthesised. Also involved in DNA replication are DNA Polymerase I which replaces primers with nucleotides, and DNA Ligase which joins fragments of DNA together.
