안녕하세요 학생 :)

열심히 공부한다니 너무 힘이 나네요 ! 이제 2달여 남았는데 응원합니다 :) 
위의 그림 이지요?
보라색 박스는 direct contact이고, 빨간색 박스는 paracrine signaling
direct contact signalling 과  paracrine signaling 둘다 short distance siganling으로 분류한답니다 

이해 되었지요? 그럼 이 문제 한번 풀어볼래요? 😃
Vertebrate immune responses involve communication over short and long distances. Which of the following statements best helps explain how cell surface proteins, such as proteins and T cell receptors, mediate cell communication over short distances?

(A) The proteins receive electrical signals from nerve cells.

(B) The proteins leave the cell and travel in the bloodstream to other cells.

(C)The proteins interact directly with proteins on the surfaces of other cells.

(D) The proteins bind to molecules secreted by cells located in other parts of the body.

지금 이 문제는 보라색 박스안을 이야기하는거지요? 답은? C 입니다 :)

맞았나요? 🥰👍 우리 학생 화이팅이에요!
