Answer:
The cytoskeleton is a network of fibers that forms the "infrastructure" of eukaryotic cells, prokaryotic cells, and archaea. In eukaryotic cells, these fibers consist of a complex network of protein filaments and motor proteins that help move cells and stabilize the cell.
Explanation:
Function:
It helps the cell maintain its shape and provides support to the cell.
Various cellular organelles are held in place by the cytoskeleton.
It helps in the formation of vacuoles.
The cytoskeleton does not represent a static structure but is able to disassemble and assemble its parts in order to enable the internal and overall mobility of the cell.
The cytoskeleton contributes to cell migration because cell motility is required for tissue construction and repair.
The cytoskeleton helps transport communication signals between cells.
In some cells, it creates cell bulges, such as cilia and flagella.
Cytoskeletal structure
:
The cytoskeleton is composed of at least three different types of fibers: microtubules, microfilaments, and middle filaments.
These fibers differ in their size, and the microtubules are the smallest and the microfilaments are the thinnest.
They are symmetrically arranged.
The right answer is C. Breaking the bonds in a monosaccharide.
This phenomenon is called glycolysis.
Glycolysis is a catabolic way of transforming glucose (monosaccharide) into energy.
Glycolysis is an energy-releasing process taking place in the cytoplasm of all cells, during which glucose is degraded to provide energy. The first steps require an investment of two molecules of ATP, but the following steps will produce four.
Answer:
A., Vision. Eyes contain two types of photoreceptors called rods and cones.
