Yesterday after I bought coffee; the clerk stamped on my cellphone. How cool it was! My first time! It looks like a stamp we used in the past, but there are many small dots at the bottom. You touch the screen of your cellphone to tell it what to do, and this is also the way smart stamps work. When people use a smart stamp, they hold the top part of the smart stamp. The small electrical charge from people's hands goes through it to the dots at the bottom. Then, the smart stamp tells your cellphone messages with them. The dots of different stores are in different patterns. no alla lil est sill lo busolos With smart stamps, stores don't have to make stickers or cards, and people don't have to keep those things.

問4. 為什麼胰島素先上升後下降 而升糖素持平? 我以為在沒有澱粉素的情況下 升糖素應該上升 因為胰島素一直促進肝醣合成 而升糖素要適時促進肝醣分解之類的 我以為他們的走向會差不多?

※2.~4.題為題組: 穿飄學味當( 胰臟具有a 及B 兩種內分泌細胞,其中a細胞分泌升糖素,B細胞則分泌胰島素。 胰島素的分泌直接受到血糖濃度的調控。科學家發現,β細胞可感知周邊環境的葡 萄糖。當葡萄糖濃度超過閥值時,B細胞會開始進行分泌活動。反之葡萄糖濃度低 於閥值時,B 細胞則停止分泌。β細胞在分泌胰島素時,也會同時分泌另一種名為 肝澱粉素(amylin)的激素,此激素會抑制升糖素的分泌,但注射能與澱粉素結合的抗 體後,澱粉素與其受體的結合會被完全阻斷,在沒有澱粉素作用的情況下,a 細胞 進肝 4 則會持續分泌升糖素。請根據所學知識及以上所提供的資訊來回答 2. ~ 4. 題。 羊) 胰:使血糖転為肝糖.肝糖变多升糖素:使肝糖転為血糖.【111分科】 ( ) 2.胰島素和升糖素對肝細胞內肝醣(糖)的作用分別為何?
