Carbonic anhydrase is an enzyme involved in the reaction of carbon dioxide with water to form a molecule that dissolves well in the liquid part of blood. how does carbonic anhydrase affect this reaction? a) by changing chemical products of the reaction b) by increasing the time needed for the reaction to occur c) by decreasing the amount of energy needed to complete the reaction

The right answer is C) by decreasing the amount of energy needed to complete the reaction

Carbonic anhydrase is an enzyme found in all our cells. It is a protein with a mass of 29,000 daltons, consisting of a chain of 264 amino acids. The presence of a Zinc atom is necessary for its activity.

It catalyzes (accelerate) the addition reaction of a molecule of water on a molecule of carbon dioxide to give the carbonic acid which dissociates at physiological pH into a bicarbonate ion and a proton. This reaction is reversible and results in a state of equilibrium that enzymatic catalysis does not change.

Carbonic anhydrase is an enzyme involved in the reaction of carbon dioxide with water to form a molecule that dissolves well in the liquid part of blood. Carbonic anhydrase affects this reaction by decreasing the amount of energy needed to complete the reaction because when the amount of energy is decreased then it will dissolve well in the liquid part of blood otherwise, it will not react.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
