What method carries molecules and pump molecules or form channels through which specific molecules pass across the plasma membrane?
Active transport is a method that carries molecules across the plasma membrane against the concentration gradient. This process uses energy, usually in the form of ATP, to pump molecules or form channels through which specific molecules can pass. Examples include the sodium-potassium pump and ion channels.
What type of protein is used to carry other molecules?
Carrier proteins are types of proteins used to carry other molecules, such as ions or small molecules, across cell membranes. These proteins can bind to specific molecules and transport them from one side of the membrane to the other. Examples include ion channels and transporters.
What are 4 examples of comparing atoms and molecules?

Give examples of three different heteronuclear diatomic molecules using hydrogen and atoms from only group 7 of the periodic table?
HCl HBr HF
What three examples of stored energy come from photosynthesis?
Three examples of stored energy from photosynthesis are glucose, starch, and cellulose. These molecules store energy in the form of chemical bonds, which can be broken down through cellular respiration to release energy for various metabolic processes.
