Question

biology l fall final
match each type of transport with the correct label.
high to low concentration, with the gradient
no energy needed
low to high concentration, against the gradient
atp energy needed
active transport passive transport

Explanation:

Step1: Recall transport types

Passive transport moves from high to low concentration (with gradient) and needs no energy. Active transport moves from low to high (against gradient) and needs ATP energy.

Step2: Match each description

• "High to Low concentration, with the gradient" → Passive Transport (moves down concentration gradient, no energy).
• "No energy needed" → Passive Transport (defining feature: no energy input).
• "Low to High concentration, against the gradient" → Active Transport (moves against gradient, needs energy).
• "ATP energy needed" → Active Transport (ATP provides energy for active transport).

Answer:

• "High to Low concentration, with the gradient" → Passive Transport
• "No energy needed" → Passive Transport
• "Low to High concentration, against the gradient" → Active Transport
• "ATP energy needed" → Active Transport
