Spring Break!

Spring break was much needed! I was able to sleep in a loootttttt....which I loved!! (:
I also got to hang out with Caitlin quite a bit (there were only likeeeee three days we didnt hang out?)

• Yea it was awesome(:

I was able to go to Gus's Original, which was YUMMYYYYYYY!

I also worked more which meant more money! woo sorta ha

Uhhmmmm....I went to the musuem with Decker and Steven for physics

Other than that my spring break was pretttyyyy chilll. I didn't go anywhere but that's alright, hopefully I can next year!

hmm

So this year...us seniors are going on a class trip. I think that is so awesome! I'm so excited to go to the aquarium and the musuem! Even though we don't get to pick our groups I think it will be a great memory with our class! It's definitely worth going. I didn't really know what else I wanted to write about so I just figured I would write about how an awesome class gets to go on an AWESOME TRIP!

Diffusion, Active Transport, and Osmosis; stuff you need to know sophmores

Hey sophmores! Mr. Landry tells us that you guys need to know diffusion, active transport and osmosis! So let's get started (:

Diffusion - Basically saying that particles are spread out evenly. Diffusion can be broken down into two things; simple and facilitated diffusion.
Both simple and facilitated diffusion move from HIGH to LOW concenctration and NO ENERGY is needed for these and are called passive transport because no energy is needed. Facilitated diffusion is different because it needs help, where as simple diffusion doesn't need help. The help comes from protein channels, they help move specific molecules across the cell membrane.

Alright, now it's time for Osmosis! Osmosis is basically diffusion of water. Osmosis also travels from HIGH to LOW concentration and no energy is needed still, so it is passive transport as well.

Now we need to cover Active transport. Active transport is where cells may have to move molecules AGAINST concentration gradient. So in other words in active transport the molecules more from LOW to HIGH concentration. Active transport does need energy (ATP) because it is moving from low to high concentration. Active transport uses a protein pump or proton pump.

REMINDERS!!!!!
Diffusion - High to low concentration and no energy is needed this is a passive transport.
Osmosis - Diffusion of water, high to low concentration, also passive transport because no energy is needed.
Active transport - Low to high concentration and energy IS NEEDED!

Which organelle to be...

Hmm...well I know a lot of people would like to be the ribosomes because they do so much! But I would prefer the rER, because it holds so many ribosomes. Once the rER makes secretory protiens it can keep them seperate from the proteins made from free ribosomes. Those secretory protiens then get shipped of in the vesicle because the rER is in charge of that. (: Oh! The rER also is a membrane factory for the cell and grows in place by adding membrane proteins and phospolipids to its own membrane.

I think the enzyme lab was a good lab to start off with, especially with a titration in it. Although the concentrations turned out to be a pain in the butt, we were still able finish the lab with time left! We had enough time to do more experiments as well. We figured that the enzyme (catalase) worked too well because it was too concentrated. Our whole first day was just finding the base line. We re-did the base line the second day, and it took way less time than the first day did. This lab really helped me understand the enzyme speeding up reactions!

The topic I'm most looking forward to is the biochemistry we're doing right now! (: This will help me know if this will be the thing I want to do in college or not. I loveeeeeee chemistry, so I'm hoping that I will love this as well. I'm actually excited for most of the topics. They all sound interesting to me(:

Well...this is my first blog ever! I love science. I love to cheer, and I've been cheering since 1st grade. I really love the color blue. (: I'm taking this course because I'm going to need it for my major in college. I'm going to Grand Valley next year and I plan to pursue cell and molecular biology or microbiology. I'm hoping to get a head start for my classes, and by taking this and passing the AP test, I can get ahead.
