Three common functions of cell membrane proteins
What are:
- Junctions – Serve to connect and join two cells together
Enzymes – Fixing to membranes localises metabolic pathways
Transport – Responsible for facilitated diffusion and active transport
Recognition – May function as markers for cellular identification
Anchorage – Attachment points for cytoskeleton and extracellular matrix
Transduction – Function as receptors for peptide hormones

Name and function of this structure.
Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope. Centrioles play a role in organizing microtubules that serve as the cell's skeletal system

Enzyme process being displayed in the image below:
What is induced fit?
600
Name and function of the three major types of RNA used in protein synthesis.
What are:
(1) mRNA - carries the DNA gene (message) to the ribosome where it will be read and expressed
(2) rRNA - makes up the part of the ribosome that activity builds the polypeptide from amino acid monomers (E, P, and A sites)
(3) tRNA - transfers amino acids from where they are in the cytoplasm to where they are needed on the ribosome to build the new polypeptide.
