Inside your cells, tiny protein “delivery workers” are walking nonstop. They’re called kinesin — motor proteins that use energy (ATP) to carry important cargo like brain chemicals, energy units, and repair materials across microscopic highways. No delivery = no function. Right now, billions of these molecular walkers are moving inside you… keeping you alive. Every thought. Every movement. Every heartbeat. 🧬 Your body is never still. #viyalum #wellnesstips #cellular #mitochondria

Mitochondria, the powerhouses of the cell, were once free-living bacteria.

*Vídeo meramente ilustrativo*. As células possuem diferentes organelas, cada uma com funções específicas que mantêm o funcionamento celular. A mitocôndria é responsável pela produção da maior parte do ATP, a principal fonte de energia da célula. Ela realiza etapas importantes da respiração celular e possui seu próprio DNA, o que sugere uma origem evolutiva associada a antigas bactérias que passaram a viver dentro das células. O retículo endoplasmático rugoso (RER) está associado à síntese de proteínas destinadas à secreção, à membrana celular ou a outras organelas. Ele recebe esse nome porque possui ribossomos aderidos à sua superfície. O centríolo participa da organização do citoesqueleto e da formação do fuso mitótico durante a divisão celular, contribuindo para a separação adequada dos cromossomos. O aparelho de Golgi atua na modificação, no empacotamento e na distribuição de proteínas e lipídios produzidos na célula. Essas moléculas podem ser direcionadas para diferentes destinos, como a membrana celular, lisossomos ou secreção para fora da célula. O lisossomo é uma organela rica em enzimas digestivas que participa da degradação de partículas, microrganismos e componentes celulares envelhecidos, permitindo a reciclagem de materiais dentro da célula. O retículo endoplasmático liso (REL) está envolvido principalmente na síntese de lipídios, no metabolismo de substâncias e no armazenamento de cálcio em determinados tipos celulares, como células musculares. O vacúolo é uma estrutura relacionada ao armazenamento de água, íons, nutrientes e resíduos. Em células vegetais, costuma ser grande e também contribui para a manutenção da pressão interna da célula. Os ribossomos são responsáveis pela síntese de proteínas a partir das informações contidas no RNA mensageiro. Eles podem estar livres no citoplasma ou associados ao retículo endoplasmático rugoso. O núcleo é a organela que abriga o material genético da célula. Nele estão as moléculas de DNA que controlam a expressão gênica e coordenam diversas atividades celulares, como crescimento e divisão.
