What is the function of the large central vacuole
Rudik [331]

Answer:Una vacuola es un orgánulo celular presente en todas las células eucariotas vegetales. También aparece en algunas células procariotas y eucariotas animales. Las vacuolas son compartimentos cerrados o rodeados por la membrana plasmática ya que contienen diferentes fluidos, como agua o enzimas, aunque en algunos casos puede contener sólidos, por ejemplo azúcares, sales, proteínas y otros nutrientes. La mayoría de las vacuolas se forman por la fusión de múltiples vesículas membranosas. El orgánulo no posee una forma definida, su estructura varía según las necesidades de la célula en particular.

La célula vegetal inmadura contiene una gran cantidad de vacuolas pequeñas, que aumentan de tamaño y se van fusionando en una sola y grande a medida en que la célula va creciendo. En la célula madura, el 90 % de su volumen puede estar ocupado por una vacuola, con el citoplasma reducido a una capa muy estrecha junto a la pared celular.

What do your cells have to overcome the problem of needing high activation energy?
Nana76 [90]

Answer: They use enzymes.

Explanation:

Cells employ enzymes to drive and speed up their chemical reactions without being used up themselves. They are the only macromolecular biological catalysts that can start a reaction using the smallest available heat energy, thus overcoming the issue of needing high activation energy. Enzymes work by converting specific substrates to required product by binding them to their active site.
