URGENTEE!!! POR FAVOR!!! Quais sao as principais funções citoplasmáticas? Qiferencie conceitualmente as duas principais estrutur
DerKrebs [107]

Answer:

A função do citoplasma é fornecer sustentação esquelética para a célula através da estrutura composta por filamentos e túbulos proteicos. Além disso, todo o conjunto de estruturas mergulhadas no citosol apresenta bastante dinamismo, fato que possibilita à célula realizar alguns movimentos.

No citoplasma, ainda há membranas que atuam como verdadeiras usinas intracelulares, que fornecem energia indispensável à manutenção da vida.

Outro fato que você deveria saber sobre o citoplasma é que ele preenche todo o interior das células eucariontes, sendo delimitado pela membrana plasmática. Já nas células procariontes, o citoplasma fica entre a membrana plasmática e o núcleo da célula.

irina [24]

Answer:

C. Nucleotides

Explanation:

Nucleic acids are macromolecules which are polymers of nucleotides. There are two types of nucleic acids namely: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleotides are the building blocks of nucleic acids.

A nucleotide is made up of three components:

- A phosphate group

- A five carbon sugar called pentose sugar. In RNA the sugar is ribose sugar and in DNA the sugar is deoxyribose sugar.

- Nitrogenous bases: There are four different types of bases in DNA: adenine, guanine, cytosine and thymine. In RNA thymine is replaced by uracil. Adenine and guanine are purines whereas cytosine, thymine and uracil are pyrimidines.

Nitrogenous base and sugar together are called nucleoside and when phosphate is also attached then it is called nucleotide.
