yes - Answer is testosterone lipid soluble testosterone - Answer readily passes through the cell membrane and binds to a receptor in the cytoplasm. the hormone and receptor then enter the nucleus and act as a transcription factot voltage-gated calcium channels in the membrane open - Answer what is a direct result of depolarizing presynaptic membrane of an axon oxygen gas - Answer in photosynthesis, atom goes from water to pump - Answer whenever this term is used, active transport occurs d...

AP Biology Exam with Answers Active Transport - Answer>>The movement of particles across a selectively permeable membrane against its concentration gradient. It requires lots of energy - hence the name "active" transport. Selectively Permeable Membrane - Answer>>A membrane that allows only specific molecules or ions to enter through it through diffusion or facilitated diffusion.
