What is enzyme, a substrate and competitive enzyme inhibition?

Biology
1 answer:
Vilka [71]3 years ago
8 0

Answer:

Enzyme: A biomolecule that speed up the rate of chemical reactions without being used up.

Substrate: A substance or chemical that enter the chemical reaction and is being converted into a new substance  (product).

Competitive enzyme inhibition: Inhibition of enzyme's activity by binding of inhibitor to substrate binding site of the enzyme.

Explanation:

Enzymes are the biomolecules that serve to increase the rate of reactions by lowering down the required activation energy. The enzyme is never used up during reactions.  

Substrates are the chemicals that undergo a chemical change and produce products.  

For example, Glucose is the substrate for hexokinase enzyme and is converted into glucose 6 phosphate (the product).

When the inhibitor competes with the substrate for the binding site on the enzyme and does not allow the substrate to bind to the enzyme, the process is called competitive enzyme inhibition. It can be overcome by increasing the concentration of substrate in the system.

What would you expect to be the final plant height for a plant grown in eight hours of light?
Nataly [62]

Answer:

Insufficient information to generate conclusion

Explanation:

It is really difficult to answer this question based on provided data. Rather speculations can be made. This is because of several reasons. The height of plant varies for different plant species. Likewise, it is really difficult for any plant species to the height of 5 inches (the lowest given option) within period of 8 hours only. It needs 8 hours light for several days to reach this much of height even for studied model plants such as arabidopsis. Thereon, each plant species would need different number of days.

On the other hand, it is important to consider that sunlight is a vital parameter for plant cells to elongate and multiply. This is because of the fact that plant use sunlight to fix carbon dioxide into the carbohydrates which is used in many cellular processes including cell division and growth. However, metabolic machinery in different plants works at different rates. Based on these reasons, it is super difficult to pick one option out of the given information to answer this question. Hope this helps.

The extra cellular matrix on most connective tissues is made up of predominantly fibers and what?
dalvyx [7]

Answer:

The correct answer will be- proteoglycans and the glycoproteins

Explanation:

The connective tissue forms a very large proportion of the total mass of a body. The connective tissue plays a distinct role in the body like the movement of the cell, mechanical support, wound healing but the main role is to connect different tissues of the body.

The property of the connective tissue is determined by the amount and type of the extracellular matrix present which contains three main components which are the fibres like collagen, glycoproteins and the proteoglycans.

Thus, proteoglycans and glycoproteins are the correct options.

una pareja cuya madre es heterocigota para el grupo sanguineo a y su espoco es homocigoto B. Determina ¿que tipo de sangre tendr
pochemuha

Answer:

1/2 IAIB, 1/2 IBIB (es decir, 50% IAIB  y 50% IBIB)

Explanation:

El grupo sanguíneo está determinado por un gen que posee tres diferentes variantes o formas alélicas:

alelo A: IA

alelo B: IB

alelo O: IO

Los alelos IA y IB son codominantes entre sí, es decir, un portador de ambos alelos será de grupo sanguíneo IAIB. Por otra parte, tanto el alelo IA como el alelo IB son dominantes del alelo IO recesivo. En este caso, el cruzamiento entre un individuo heterocigota IAIB con un individuo homocigota IBIB dará como resultado una descendencia 1:1 de heterocigotas IAIB y homocigotas IBIB (es decir, 50% IAIB  y 50% IBIB), ya que la madre producirá ambos tipos de gametos en proporciones equivalentes (1/2 IA  y 1/2 IB), mientras que el padre sólo producirá gametos IB.
