No, enzymes are catalyst proteins.
Carrier Proteins
Carrier proteins are sometimes used during passive transport.
cell membrane
Energy, versus passive in which energy is not used.
Yes they may. Passive or Active can both use integral proteins to facilitate transport. When the substances are transported from low to high concentration it requires additional energy (i.e. active transport); while passive transport move molecules from high concentration to low and do not need additional energy (passive transport). Integral proteins are membrane proteins that have transmembrane domain, but whether it will need energy (ATP, photons or conc. gradient) to change from inactive form to active form depends on the substance that it is transporting.
Carrier proteins can be involved in passive transport.
passive
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.

Transport proteins and carrier proteins
cell membrane
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
