Question

match the process to the letters in the diagram above: osmosis: facilitated diffusion: simple diffusion: active transport: moves through a transport protein: does not require energy: complete each of the statements below. circle the words and fill in the blanks. a. the oxygen (o₂) and carbon dioxide (co₂) in process a are moving (with / against) their concentration gradient from concentration to concentration. b. the water (h₂o) in process c is moving (with / against) the concentration gradient from concentration to concentration. c. the potassium (k⁺) in process d is moving (with / against) the concentration gradient from concentration to concentration.

Explanation:

Oxygen and carbon - dioxide move by simple diffusion which is with the concentration gradient. Water moves by osmosis (a type of diffusion for water) with the concentration gradient. Glucose moves by facilitated diffusion through a transport protein with the concentration gradient. Potassium moves by active transport against the concentration gradient using energy (ATP).

Answer:

a. The Oxygen ($O_2$) and Carbon Dioxide ($CO_2$) in process A are moving (WITH) their concentration gradient from concentration to concentration.
b. The Water ($H_2O$) in process C is moving (WITH) the concentration gradient from concentration to concentration.
c. The Potassium ($K^+$) in process D is moving (AGAINST) the concentration gradient from concentration to concentration.
Simple Diffusion: A
Facilitated Diffusion: B
Osmosis: C
Active Transport: D
