Which enzyme catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase (PFK)
Which steps of cellular respiration occur in the cytoplasm?
glycolysis
Glucose is converted to what during glycolysis?
Glucose is converted to pyruvate during glycolysis.
What is the importance of a rate-limiting enzyme?
A rate-limitingenzyme's place as first in a series is important because if an enzyme at some point in the sequence were rate-limiting,an intermediate chemical in the pathway might accumulate.
Organisms that ferment have a greatly increased rate of glycolysis compared to those that do not ferment Why?
Organisms that ferment have a greatly increased rate of glycolysis because fermentation is an anaerobic process that allows for the regeneration of NAD+ required for glycolysis to continue in the absence of oxygen. By increasing the rate of glycolysis, these organisms can rapidly produce energy (ATP) for survival under anaerobic conditions.
Which of the following enzymes catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase
Which enzyme catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase (PFK)
Which of the following is correct regarding glycolysis?
The "committed" reaction is also the rate-limiting reaction
What is a rate governed process in Chemical Engineering?
A rate-governed or rate-limiting process is a process in which there are several steps; however, the rate of one or more steps is much slower than all the others. The rates of the previous steps and following steps are assuming to be infinite, and the rate of the process only depends on the rate-limiting step(s).
Which steps in glycolysis are irreversible?
The steps in glycolysis that are irreversible are catalyzed by the enzymes hexokinase/glucokinase, phosphofructokinase, and pyruvate kinase. These steps are key regulatory points in glycolysis ensuring the forward flow of glucose through the pathway.
What is the slowest chemical reaction?
Chemical reactions involve the breaking and forming of bonds, and the rate at which this happens can vary widely. Some reactions, like rusting, can be very slow, taking years to noticeably occur. However, reactions can be sped up by changing conditions like temperature and pressure.
What goes in and comes out of glycolysis?
In glycolysis, glucose (a 6-carbon sugar molecule) goes in and is converted into two molecules of pyruvate (a 3-carbon compound). This process also produces ATP (energy) and NADH (a molecule that carries high-energy electrons).
How many steps are required to complete glycolysis?
Ten
Which steps of cellular respiration occur in the cytoplasm?
glycolysis
Rate limiting step of cholesterol?
The HMG-CoA Reductase reaction is rate-limiting for cholesterol synthesis.
Glucose is converted to what during glycolysis?
Glucose is converted to pyruvate during glycolysis.
What steps in aerobic respiration can process without oxygen?
glycolysis
