Phases of Mitosis
During this phase of mitosis, chromosomes align along the pole or the center of the cell
Metaphase
This type of organic molecules serves as the primary energy. its a source for living organisms and is commonly found in rice, bread and pasta
Carbohydrates
What is substrate?
Substrate is a molecule an enzyme reacts with.
What is the size of a typical abnomality
Walnut size
What is Biuret Reagent testing for?
Proteins
In this phase of mitosis, sister chromatids separate and pull away from the pole of the cell
Anaphase
This organic molecules is made up of long chains of amino acids and plays a crucial role in cellular structure
Proteins
What happens if the temperature exceeds the comfort zone of an enzyme
It denatures.
What is cancer?
It is a disease characterized by uncontrolled spreading and division of cells in the body
What is agglutination?
The clumping of particles
This phase comes before mitosis and involves the replication of DNA
Interphase
Cholesterol belongs to this category of organic molecules, which are hydrophobic and serve as energy storage
Fats Or lipids
What happens to the enzyme if it denatures and what are the effects?
The enzyme will slowly bend out of shape and it will not be useable anymore.
Why do you lose hair when going through chemotherapy?
You lose hair because chemotherapy targets rapidly driving cells in the body so the faster a cell divides the higher chance of it getting eliminated.
When you use iodine, what are you testing for and what color will it be if it is positive?
Starch and black blue
This phase of mitosis is characterized by the condensation of chromatin into visible chromosomes and the disappearance of the nuclear membrane
Prophase
This is a primary molecule for storing and transmitting genetic information in living organisms?
Nucleic acids
What do enzymes act like during digestion and what do they do?
Enzymes act like a catalyst during digestion and they speed up the chemical reactions of breaking things down
What are at least 4 ways of preventing cancer?
Maintain a healthy diet, exercise daily, protecting your skin, avoid smoking, limiting the consumption of alcohol, and get screen tests.
What are you testing for when you use brown paper and how does this test work?
Its testing for lipids and it works because the paper is permeable to these substances and when a drop of liquids containing fats or oils makes contact with the paper it will leave a translucent or greasy stain.
The chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form.
Telophase
This serves as the main component of the cell membrane and has a hydrophilic head and hydrophobic tail structure
phospholipids
What does active transport require and what does it allow?
It required ATP and it allows the cell to maintain specific concentrations of molecules inside and outside of the cell with is crucial for correct cellular function.
What is the difference between malignant tumors and benign tumors.
Malignant tumors are cancerous, grow rapidly, and will disrupt other organs. Benign tumors aren't cancerous, grow slowly, and usually are not life threatening but if it grows large enough it will cause harm.
What is the procedure of determined the concentration of glucose in a solution using Benedict's reagent.
1. Get a few clean test tubes and add equal amounts of solution to each one
2. Add equal amounts of benedicts and stir thoroughly
3. Put all test tubes in boiling water and wait
4. Observe the color changes (if its brick red its positive)
