Question

a major role for mitochondria is to *
synthesise fatty acids, phospholipids & steroids
deliver lipids and proteins to plasma membrane for secretion
synthesise proteins from amino acids
produce atp (adenosine triphosphate)
examine the diagram. what type of transport is occurring during this
process
insulin
insulin
glucose
receptor
glut4

Explanation:

For the first question: Mitochondria are known as the "powerhouses" of the cell. They produce ATP (adenosine triphosphate) through processes like oxidative phosphorylation. Fatty acid synthesis occurs in the cytoplasm and endoplasmic reticulum. Lipid and protein delivery to the plasma membrane for secretion is related to the Golgi apparatus. Protein synthesis from amino acids occurs in ribosomes.
For the second question: Glut4 is involved in facilitated diffusion of glucose. Facilitated diffusion is a type of passive transport where molecules (like glucose) move across the cell membrane with the help of transport proteins (in this case, Glut4) down their concentration gradient (from an area of higher glucose concentration outside the cell to an area of lower glucose concentration inside the cell).

Answer:

For the first question: produce ATP (adenosine triphosphate)
For the second question: Facilitated diffusion
