Catechol oxidase is a plant enzyme that converts catechol to benzoquinone. Catechol is found within the vacuole of the plant while the enzyme is in the cytoplasm. When a fruit gets damaged (bruised), the vacuoles within the cells break and release the chemical into the cytoplasm. Benzonoquinone is brown in color and toxic to bacterial and therefore prevents the decay of the damaged cells. If you increase the amount of catechol within the cytoplasm of an apple then it is likely that
You will increase the amount of benzoquinone

A flask containing photosynthetic green algae and a control flask containing water with no algae are both placed under a bank of lights, which are set to cycle between 12 hours of light and 12 hours of dark. The dissolved oxygen concentrations in both flasks are monitored. Predict what the relative dissolved oxygen concentrations will be in the flask with algae compared to the control flask.
The DO in the flask w/ algae will be higher in the light but lower in the dark.

Your group was assigned to work with the chemical Camptothecin, which is derived from the barks and stems of Camptotheca acuminate, known as the Happy Tree. It is a topoisomerase inhibitor that induces desynapsis of paired chromosomes during meiosis. Where would cellular division be arrested?
Prophase 1

As we know, inhibitors prevent enzymes from working by blocking the active site. Dr. Oz claims that a chemical extracted from a WKB will act as an inhibtor to block starch (large carb) from attaching to amylase (digestive enzyme) and therefore, stop the product glucose from being made. Since our body has a hard time breaking down starch, starch would then pass naturally through our digestive system. An experiment was set up to test his claim.
Dr. Oz claim is false and does WKB extract does not break down starch.

You are a lawyer and have a case where Miss Scarlet is trying to figure out who fathered her child, Junior, during a scandolous love affair. Below is the given list of possible fathers. You know that the child's blood type is Type ), and Miss Scarlet is Type B. You are worried that blood typing alone wont help solve the battle so you ask all parties involved for some traits. Mom has attached earlobes (recessive) and straight hairline (recessive) while Junior has attached earlobes (recessive) and a widow's peak (dominant).
The Butler - Type A, non-attached earlobes, widow's peak

Vinblastine from the rosy periwinkle and taxol from the Pacific Yew are two natural plant products that have been used successfully in the treatment of a wide range of cancers. These chemicals work by interfering with mitosis but through different methods. Vineblastine inhibits mitosis by preventing the assembly of the spindle. Taxol promotes microtubules synthesis and binds to the microtubule preventing the depolymerization (retraction) of the spindle fibers. Based on your knowledge of mitosis, taxol would slow/stop mitosis at the ____/____ transition
Metaphase/Anaphase

Catechol oxidase is a plant enzyme that converts catechol to benzoquinone. Catechol is found within the vacuole of the plant while the enzyme is in the cytoplasm. When a fruit gets damaged (bruised), the vacuoles within the cells break and release the chemical into the cytoplasm. Benzonoquinone is brown in color and toxic to bacterial and therefore prevents the decay of the damaged cells. Catechol oxidase in potatoes act best at a temp of 40 degrees celcius, but is not active at a temp of 100 degrees Celscius Why?
the optimal temperature helps to maintain the enzymes tertiary structure.

Insecticides in the various "classes", such as chlorinated hydrocarbons (DDT), organophosphates, carbamates, and synthetic pyrethroids, differ in their effects on plants. A new insecticide on the market claims to breakdown chlorophyll and is known as a photosynthetic inhibitor. PLants that have been exposed to photosynthesis-inhibiting herbicides will begin to appear yellow on the veins and around the edges of the oldest leaves, which will be followed by similar damage to younger leaves. Yellow spots may also appearo n affected leaves. If chlorophyll in a plant is destroyed, what is directly affected?
Photochemical reaction: the electron transport chain which directly uses light energy to split water.

A genetics engineer was attempting to cross an elephant and a rhino. She predicted a phenotypic outcome of the traits she was observing to be in the following ratio 3 trunk only: 5 horn only: 8 both trunk and horn
When the cross was performed and she counted the individuals she found 205 with trunk only, 410 with horn only and 625 with both. According to the chi-Square test, did she get the predicted outcome?
No, it does not follow her prediction.
