Is it true formation of multiple replication forks tends to slow down DNA replication?
No, the whole point in forming multiple replication forks is to reduce the time it takes to replicated DNA by replicating several sections of DNA at the same time, so that each polymerase enzyme has to copy less of the DNA. As a result replication finishes earlier than it would if one polymerase were to replicate the entire strand (as it would operate at the same speed - about 1000 base pairs per second). The human genome has about 20,000 origins for replication, which will produce 20,000 replication forks. It is necessary to have this many because the human genome is so large (3.3 billion base pairs). Without 20,000 origins, DNA replication would take close to 20,000 times longer.
How fast or rate is the catalase enzyme?
6 million vols a second at 30 degrees c
Where is the substrate that binds to an enzyme?
A substrate molecule needs to interact with the enzyme's active center (known as "active site") for the enzyme mediated catalytic conversion of substrate into product. Some times, this could or may bind to a second site of an enzyme named, "allosteric site" that would not form the product.
What enzyme can convert 40 million molecules of hydrogen peroxide to harmless water and oxygen every second?
Catalase
What is the biological function?
Lipase is a enzyme used to cleave lipids, usually membrane lipids. Phosolipase C is a power second messenger used in intercell signaling. Lipase is a enzyme used to cleave lipids, usually membrane lipids. Phosolipase C is a power second messenger used in intercell signaling.
When does replication in a cell take place?
replication in the cell take place in the second phase which is the metaphase.
DNA replication is also called?
DNA replication is the second part of inter-phase where the cell makes an exact copy of the DNA in its cell. Please see the answer to the related question below..
How many substrate molecules does a typical enzyme act on per second?
A single enzyme molecule can act on about 1000 substrate molecules per second.
In what part of the cell cycle does replication occur?
DNA replication occurs during Interphase. This is not normally part of the cell division cycle but interphase must occur before subsequent stages such as prophase and metaphase can occur.

How many nucleotides do humans get per second?
DNA replication in humans occurs at a rate of ______ nucleotides per second.
What do you call the process when DNA zips itself and makes a second copy?
replication
What is the role of ubiquinone in the electron transport chain?
Ubiquinone carries electrons from the first enzyme complex to the second enzyme complex
What are the 3 factors that can change the rate of enzyme reaction?
The first factor is Enzyme concentration or subtrate concentration.The rate of enzyme action is directly proportional to to the availability of enzyme provided the substrate concentration unlimited.Or the rate is directly proportional to the substrate concentration if enzymes are limited but if enzyme concentration is kept constant then upto the certain level the increase in substrate amount will no longer increase the rate of enzyme action. Second factor is temperature.The rate if an enzyme action is always directly proportional to the increase in temperature but upto the specific limit called as optimum temperature. Third factor is the pH value.Enzymes can work efficiently over a narrow range of pH called as Optimum pH.A minor change in pH value can denature the enzyme.
Why must animal use more energy to produce a second enzyme?
because there are animals
What makes enzymes in the digestive system?
first salivary glands in the mouth which produce an enzyme which help in digesting carbohydrates. second gastric gland in stomach produce an enzyme called pepsin which help in digesting protein third in the pancreas which produce the three types of enzymes that digest all types of food .
How fast or rate is the catalase enzyme?
6 million vols a second at 30 degrees c
