Are all the sides to a pentagon the same size?
Yes,all of the sides of a polygon are the same shape.
A shape that has six sides is called what?
A six sided shape is called a hexagon.If all the sides have the same length and all the internal angles are the same it is a Regular hexagon.
Is a rhombus a regular shape?
yes No it is not. All the angles of a regular shape must be the same and that is not the case with a rhombus.
Do all rectangles can be cut in half vertically or horizontally to make two smaller rectangles that are the same size and same shape?
Yes, they will be the same size and shape as each other.
All angles are congruent?
Um, I'm not sure what that is soposed to mean, but if this helps, in a shape, not all angles are congruent unless they are all the same size and shape.
What are all the enzymes that use the lock and key model?
ALL enzymes use the lock and key model!
What is the purpose of having enzymes within a cell?
Enzymes are biomolecules that catalyze (i.e., increase the rates of) chemical reactions. Almost all enzymes are proteins. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
Which of the following statements about enzymes is not true A are catalysts B almost all enzymes are proteins C operate most efficiently at optimum pH D destroyed during chemical reactions?
Enzymes are not destroyed during chemical reactions.
A characteristic shared by all enzymes hormones and antibodies is?
the shape of there molecules :)
Enzymes are very specific in their choices of substrates because each different enzyme has an active site thaT?
Substrates are compounds with an unique shape - also called its conformation. So the enzyme active zone that binds with the compound fits the substrate like a hand and a glove fit each other. Just as a right hand couldn't comfortably use a left handed glove neither can all substrates fit in an enzyme active zone.
Why are enzymes said to be specific?
Enzymes are highly specific in their action. For example, enzyme maltase acts on sugar maltose and not on lactose or sucrose. Different enzymes may act on the same substrate but give rise to different products. For example, raffinose gives rise to melibiose and fructose in the presnce of enzyme sucrase while in the presence of enzyme melibiase it produces lactose and sucrose. Similarly an enzyme may act on different substrates like sucrase can act on both sucrose and raffinose producing different end products.
Does the active site of an enzyme have a shape that is specfic for its given substrate?
Yes all enzymes have an active site where substance are temporarily bound. All enzymes have shape that may change during catalysis. The active site of an enzyme orients its substrate molecules, thereby promoting interaction of their reactive parts.
How do enzymes affect reactions in living cells?
Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.
Are substrates proteins?
There are protein substrates, but not all substrates are proteins. Lipid, carbohydrates, nucleic acids can also act as substrates to its specific enzyme. but enzyme can be only proteins and not Lipid, carbohydrate.
A characteristic shared by all enzymes hormones antibodies is that their function is determined by the?
shape of the molecules
What group of molecules are enzymes?
Most enzymes are proteins. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.
Why are the enzymes used in cellular respiration virtually identical in all species?
the same genetic code produces those enzymes.
