A G protein will come in action, attach to the recptor protein. And b etc one phosphorylated and set on motion transduction

A G protein receptor molecule receives a ligand. This ligand causes a conformational shape changes occur within the receptor protein. What will happen next?

The Extra Cellular Matrix protects the outer membrane surface; whereas; the cytoskeleton provides internal support and structure to the cell

Animal cells do not have protective cell walls, like plant cells, as they need to be able to move or be flexible. They do have protective structures that help protect them from environmental stresses. Which statement below best identifies and explains the structures that animal cells possess?

Tumors

During the chromatin phase of DNA, the DNA is in what form?

The mitochondria are the energy producing organelles associated with ATP synthesis

Organelles play various roles within Eukaryotic cells, such as helping with protein production or structural integrity. Which organelle contains DNA and is responsible for producing ATP (which is energy for the cell) when oxygen is present within the cell?
