Verified step by step guidance

Understand the concept of 'Primary Active Transport': This type of transport requires energy, usually in the form of ATP, to move molecules against their concentration gradient.

Identify the role of ATPase: ATPases are enzymes that catalyze the decomposition of ATP into ADP and a free phosphate ion, releasing energy used for active transport.

Recognize the term 'Uniport': Uniport refers to the transport of a single type of molecule across the membrane, without coupling to the transport of another molecule.

Connect the function of calcium ATPase: Calcium ATPase uses ATP to transport calcium ions across the cell membrane, against their concentration gradient, which fits the model of primary active transport.

Differentiate from other transport models: Facilitated diffusion, secondary active transport, and simple diffusion do not require direct ATP usage for transport, unlike primary active transport.
