cellulosa

a natural sugar found in fruits and honey, often used to sweeten foods and drinks

fruktos

a basic kind of sugar that is a component of carbohydrates and provides energy for many living organisms

glukos

a short chain of amino acids linked together, which can function as a building block for proteins or act as a signaling molecule in the body

peptid

a type of pigment found in plants, algae, and some bacteria, responsible for bright red, yellow, and orange colors and important for photosynthesis and antioxidant activity

karotenoid

a substance that all living organisms produce that brings about a chemical reaction without being altered itself

enzym

the entire set of proteins expressed by a cell, tissue, or organism at a specific time under defined conditions

proteom

lipid

relating to or characteristic of mitochondria, which are organelles found in cells responsible for energy production

mitokondriell

the gel-like, semifluid substance within a cell that surrounds the organelles, providing a medium for cellular activities, including metabolism, transport of substances, and support for cellular structures

a type of tissue that lines the surfaces and cavities of organs and structures throughout the body, serving protective, absorptive, and secretory functions

epitel

a cellular organelle involved in the processing, packaging, and distribution of proteins and lipids within the cell, consisting of a stack of flattened membrane sacs called cisternae

Golgiapparaten

a tiny structure within cells that assembles proteins by reading the genetic instructions carried by messenger RNA

ribosom

a small, enzyme-filled sac in a cell that breaks down waste materials and unwanted substances

vakuol

(biology) the part of a cell that contains most of the genetic information

kärna

a plant cell organelle that uses sunlight to produce energy and make glucose through photosynthesis

kloroplast

a network of protein fibers in a cell that gives it shape, supports its structure, and aids in movement

cytoskelett

a branch of biology concerning the scientific study of the form and structure of an organism including plants and animals

(biology) taking place inside one cell or more

intracellulär

a specialized, membrane-bound structure within a cell that performs specific functions, contributing to the cell's overall structure and function

organel

a layer of actively dividing cells in plants, responsible for secondary growth by producing new xylem and phloem tissues
