What is the importance of the protein used in Method B during cellular transport? A. The channel allows small oxygen molecules to pass through the protein channel against the concentration gradient to maintain homeostasis.
B. The channel allows small carbon dioxide molecules to pass through the protein channel along the concentration gradient to maintain homeostasis.
C. The channel allows large glucose molecules to pass through the protein channel along the concentration gradient to maintain homeostasis.
D. The channel allows large carbon dioxide molecules to pass through the protein channel against the concentration gradient to maintain homeostasis
