I don't think I every mention this, but my cat Ivy die the month I graduated high school. Three years went by so fast; I'm 22yrs old now. Went to collage, transfer schools, drop out, was a bum on my parent's couch for awhile, join the navy, did two years of my four contract, went back home, got a job (min wage), and brought a car... plan on moving back to Texas before this year is over too.
I have nothing else to say
Still not sure what to do with my life though
Oh! I'm female and my name is Marisa see me as zeppelin4790 or FoxCatGirl on YouTube and FoxCatGirl on Disqus

The Role of Enzymes
Cells are possibly the smallest chemical factories in the world and yet they are exquisitely efficient and productive. They build chemical compounds (anabolism) from imported raw materials and break down larger molecules (catabolism) to access the necessary elements and energy to help maintain proper function. Cellular chemical processes are referred to as metabolism.
Metabolic reactions require a great amount of energy to take place (activation energy or EA). One way cells manage metabolic reactions is through the presence of enzymes. Enzymes are a type of protein that helps control and manage cell metabolism by making chemical reactions happen more efficiently than if the cell functioned without them. Enzymes lower the activation energy normally required for chemical reactions to take place.
Enzymes compounds are three-dimensional molecules that have special bonding areas called active sites. At the active site of some enzymes, large molecules are broken into smaller molecules (catabolism). Other enzymes bond small molecules together to make larger compounds (anabolism). The molecules and enzymes metabolizes are known as substrates.
The shape of an enzyme's active site is matched to the shape of the molecule it metabolizes. The substrate bonds to the active site and the enzyme molecule firms up the attachment. If possible, take a moment to shake hands with someone. The way hands fit together and firm up in a hand shake is similar to how an enzyme-substrate complex bonds. This is called an "induced fit."
Enzymes function best in specific conditions; environmental factors within the cell can affect how well an enzyme functions. High temperatures can denature (break down) an enzyme, changing its shape. Most enzymes work best in environments where pH range is 6 - 8. Higher or lower values in cells negatively affect enzyme function and thus cell function. An exception is digestive enzymes in the human stomach, which work best in pH 2. Some enzymes work only in the presence of two other type of compounds, cofactors (such as zinc or iron) and coenzymes (such as vitamins). Other compounds inhibit enzyme function by either blocking the active site (competitive inhibitor) or bonding to the enzyme and changing its shape (noncompetitive inhibitor).
Enzymes are often referred to as catalysts because they increase efficiency in chemical reactions without being affected. Because of enzymes, cells can manage millions of chemical reactions per second without breaking a sweat. Because of enzymes, cells can harvest energy and raw materials from the food you eat to build a better you.

Things to do at Walmat
Things to do at Walmart:
1. Get 24 boxes of condoms and randomly put them in people's carts when they aren't looking.
2. Set all the alarm clocks in Electronics to go off at 5-minute intervals.
3. Make a trail of tomato juice on the floor leading to the rest rooms.
4. Walk up to an employee and tell him/her in an official tone, "Code 3' in housewares"... and see what happens.
5. Go the Service Desk and ask to put a bag of M&M's on lay away.
6. Move a 'CAUTION - WET FLOOR' sign to a carpeted area.
7. Set up a tent in the camping department and tell other shoppers you'll invite them in if they'll bring pillows from the bedding department.
8. When a clerk asks if they can help you, begin to cry and ask, "Why can't you people just leave me alone?"
9. Look right into the security camera & use it as a mirror, and pick your nose.
10. While handling guns in the hunting department, ask the clerk if he knows where the anti - depressants are.
11. Dart around the store suspiciously loudly humming the "Mission Impossible" theme.
12. In the auto department, practice your "Madonna look" using different size funnels.
13. Hide in a clothing rack and when people browse through, say "PICK ME!" "PICK ME!"
14. When an announcement comes over the loud speaker, assume the fetal position and scream..
"NO! NO! It's those voices again!!"
15. Go into a fitting room and shut the door and wait a while and then yell, very loudly, "There is no toilet paper in here!
16. Get several bouncy balls and throw them down an aisle shouting "pikachu, I choose you!"

 | Circulatory System The circulatory system carries oxygen (hemoglobin in red blood cells carries O2) and nutrients to the cells all over the body and carries carbon dioxide and waste away from the cells. |
 | Respiratory System The respiratory system brings oxygen (O2) into the body and sends carbon dioxide (CO2) out of the body. |
 | Digestive System The digestive system breaks down food and adsorbs nutrients for the body. It is aided by bacteria that live in the intestines and help break down complex nutrients. |
 |
Nervous System
The nervous system collects and stores information from inside and outside the body. It controls the body's actions and its responses to any changes. All five senses are part of the nervous system.
|
 | Skeletal System The skeletal system gives your body structure and protects your internal organs. It stores minerals and produces blood cells in the bone marrow. |
 | Muscular System The muscular system is responsible for all of the body's movements, both voluntary (jumping, chewing, walking, etc.) and involuntary (breathing, stomach churning, etc.). |
 | Endocrine System The endocrine system produces chemical messengers called hormones that help maintain homeostasis and control growth and development. |
 | Integumentary System The integumentary system is your skin. It serves as a protective barrier around your body preventing water loss and helping to control body temperature. |
 | Immune System The immune system is made of antibodies and white blood cells that protect your body from infection. HIV attacks a special type of white blood cell known as the Helper T cell. |
 | Reproductive System The reproductive system produces the gamete cells required for sexual reproduction. The male cells are known as sperm and the female gamete cells are known as eggs. |
 | Excretory System The excretory system removes waste from the body and helps the body maintains homeostasis by preventing the buildup of excess fluid and solid material within the body. |

Student Snapshot
In my last year of High School... Very happy about this, yet still depress. Thought I'd be satisfied. Sign up for another computer software class. So what you think; got a 99.

Thoughts
I kinda feel bad that I never come on here and actually put blog posts on qm-m. However on the other end/hand, I don't want just anybody reading my thoughts. Maybe I'm merely being a tiny bit paranoid. I'm the sort of person who loves to talk and ramble on about anything. ps Gemini are awesome! I'm not the type who wants to go around deeply sharing my thoughts and emotions.
Anyway my summer vacation was completely boring; there was nothing to do. Nobody would hire me. Apparently, people thought I was turning in a joke applications because I look like I'm 12. So workers or mangers would simply throw it out. I'm 18 and still don't have a job. I'm so happy this is my last year of high school. I can finally do some interesting activties. I hate feeling like a little kid.
Nobody reads this....sad.
