rough endoplasmic reticulum
Carrier proteins can be involved in passive transport.
These proteins are likely transport proteins, such as carrier proteins or channel proteins, which bind to specific molecules and facilitate their movement across cell membranes or through the bloodstream. These proteins help to transport essential molecules like hormones, ions, and nutrients to their target destinations in the body.
Transport proteins are not responsible for the secretion. Golgi vesicles transport proteins. Proteins synthesis occur in cytoplasm.
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.
No, transport proteins are also in other organisms.
transport proteins both are carrier proteins and channel proteins

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.

The endoplasmic reticulum. Specifically the "rough" ER is the site of protein synthesis and the "smooth" ER is the site of lipid synthesis.
Proteins used in active transport are called transport proteins. These proteins are responsible for moving molecules or ions across a cell membrane against their concentration gradient, requiring energy in the form of ATP.
Transport proteins are important because they carry proteins which move molecules from one place to another around the body.
