Biology

Protein are made of:

• phospholipids

• amino acids

• covalent bones

• enzymes

Enzyme are catalyst that:

• slow down a chemical reaction

• speed yp a chemical reaction

• destroys a chemical reaction

• non of the answers are correct

the place where a subtracts binds to an enzyme is called:

• the key

• the lock

• the gate

• active site

It controls what goes in and out of the cell

• nucleolous

• nucleous

• Plasma membrane

• nuclear membrane

Is where energy is made:

• mitochondria

• nucleous

• golggi apparatus

• lysosomes

Animal cell dont have this organelle

• cell mebrane

• choloroplasts

• mitochondria

• vacuoles

A phospholipid is composed of:

• 2 basic parts

• 3 basic parts

• 4 basic parts

• 5 basic parts

This organelle act as a garbage collector in a cell

• lysosomes

• vesicles

• vacuoles

• cytoskeleton

the cell theory states that:

• not all living things are made up of cells

• only plants have cells

• the atom and not the cell is the basic unit of life

• all cells come from preexisting cells.
