Biology STAAR Review

I am learning the different cell processes.

​​Learning Goal:

1. I can investigate homeostasis through the cellular transport of molecules.

2. I can explain how matter is conserved and energy is transferred during photosynthesis and cellular respiration.

​​Success Criteria:

5C: investigate homeostasis through the cellular transport of molecules.

​

Cellular Transport

Match

Match the following transport with its function.

• Movement of molecules through a cell membrane without protein channels or energy.

• Movement of molecules via protein channels without energy.

• Movement of water molecules from a solution of high concentration to low concentration. No energy.

• Cells take in substances from outside of the cell by engulfing them in a vesicle.

• Cells move materials from the cell by engulfing them and releasing them outside the cell.

Multiple Choice

The diagram represents the movement of three different substances across a cell membrane. Moving which of these substances across the cell membrane requires energy from ATP?

• 2 only

• 3 only

• 1 and 2

• 1 and 3

Multiple Choice

Which statements best describe the difference between active transport and passive transport?

• Active transport occurs only in cells that require large amounts of energy. Passive transport occurs in all cells.

• Active transport requires ATP. Passive transport does not require ATP.

• Active transport moves substances along the concentration gradient. Passive transport moves substances against the concentration gradient.

• Active transport occurs in all cells. Passive transport requires ATP.

Multiple Choice

A diagram of removing glucose from the blood by a fat cell is shown. Which statement best describes the role of insulin and glucose-transport proteins in this process?

• They stimulate a response from white blood cells during glucose entry into the cell.

• They keep the plasma membrane flexible when glucose is removed from the blood.

• They help to maintain stable glucose levels both inside and outside the cell.

• They utilize the excess energy the cell produces to create more glucose.

Multiple Choice

Which type of movement across a cell's plasma membrane requires energy supplied by ATP?

• Passive transport

• Simple diffusion

• Active transport

• Osmosis
