I’m working on a biochemistry discussion question and need support to help me understand better.

Discussion 2 (Responses – Caffeine as a Competitive Inhibitor) You should respond to two (2) of your classmates’ posts from Discussion 2 (Week 3). Each post should be at least 100 words. Please do you just repeat what you wrote in your post during Week 1 or copy someone’s post. Try to provide additional examples to support your point. If you don’t agree with you classmate, explain why. Please DO NOT copy any of your classmate’s comments or plagiarize (you will not receive credit for doing this.

In this lesson we discussed about caffeine and its effect on the human brain.

I heard about drinking coffee to keep awake when I have preparing to take my final examination in secondary school (1999). I decided to take a cup of coffee to stay alert and study during the night. I added creamer, sugar two slices of bread. I slept just few minutes after drinking it. I discussed this with my mate and was told not to add neither sugar nor cream. Also, not to have anything with it. I managed to have it black with no added sugar or cream the next time. It tasted bitter but since I wanted to stay awake, I drank it. I slept just as the same as I added sugar and cream.

Probably my genetics are to blame! For not keeping awake after drinking black coffee with no sugar. Caffeine interacts most directly with the A1 receptor. Caffeine causes most of its biological effects via antagonizing all types of adenosine receptors (ARs): A1, A2A, A3, and A2B and, as does adenosine, exerts effects on neurons and glial cells of all brain areas.

This lesson has given me more insight about how people react to caffeine differently. I had a misconception that caffeine consumption. I did know caffeine had any health benefits apart from keeping people awake. I now know that moderate coffee consumption can help with liver disease, providing boast of antioxidants and protecting the brain against Parkinson’s disease.

I had more insight about the bad effects of caffeine.

According to the article, people get caffeine from consumption of coffee, tea, soda or chocolate

I avoid coffee even though I like the smell because it’s side effect of getting addicted and all negatives said at it. Actually, I am getting caffeine from consumption of chocolate.

This was your previous Reply: I agree that coffee can help people to stay alert and awake. Coffee can be crucial to students studying at night. Coffee-added sugar and cream react differently to individuals as one might sleep while adding these things or taking black coffee with no sugar. The genetic components of an individual might play a significant role in how caffeine reacts to the body. In addition, I feel that caffeine causes most biological impacts. Caffeine reacts differently to individuals and can be got from various things such as coffee, soda, and chocolate. Therefore, apart from keeping people awake, caffeine has numerous health benefits

Many of us rely on a morning cup of coffee or a jolt of caffeine in the afternoon to help us get through the day. Caffeine is so widely available that the U.S. Food and Drug Administration (FDA), says about 80 percent of U.S. adults take some form of caffeine every day. But caffeine does so much more than just keeping you awake. It is a central nervous system stimulant that affects your body in numerous ways. I found this week article and the videos remarkably interesting. My husband lives and breath coffee every morning. My husband started consuming coffee when he started working early morning like every other American. His first stop used to be either wawa or Starbucks. He started to realize that coffee was getting expensive, so he decided to buy his own Keurig machine and make his own coffee every morning. He drinks any amount of coffee, drink soda thinking it will help boost his energy. I guess all the years of drinking caffeine built an immunity in his body, so his system does not respond to it anymore.

This article has given me an understanding on how caffeine drinkers differ from person to person. I for one use to think that caffeine is the only way for early morning risers like my husband stay awake on their way to work, not knowing it does the opposite. And after reading the article I now know all the positive effect caffeine has on people like fight liver disease and helping with Parkinson’s disease. Before reading this article I only knew of the withdrawal some people go through after a caffeine intake, but this article gave me an insight about the positivity on caffeine.

I agree that most people rely on the cup of caffeine in the morning and afternoon to help to get through the day. In the U.S, caffeine is widely used, such that FDA says that most main consume caffeine daily. Caffeine does a lot in the human body than just maintaining the individual to be awake. In the human body, caffeine is the essential stimulant that affects the human body in various ways. Coffee drinks vary from individual to individual. Thus, caffeine has a positive e impact on individuals, such as fighting diseases such as liver and Parkinson’s diseases.
