2X

How much DNA is present in Phase III?

2X - 1X

How much DNA is present in Phase IV?

Hypotonic

What scenario are these cells in?

Isotonic

What scenario are these cells in?

Hypertonic

What scenario are these cells in?

6CO2 + 6H2O → C6 H12 O6 + 6O2

What is the equation for photosynthesis?

O2 + C6 H12 O6 → CO2 + H2O + Energy (ATP)

What is the equation for Cellular Respiration?

They wouldn’t be able to stick to the enzyme.

What will happen to the substrates when they attempt to attach themselves to the enzymes?

Chemical Energy

What form of energy is needed for Photosynthesis, and Cellular Respiration?

No.

Could this strand of DNA be found in a moose? (Yes or No)

They are 3 distinct monosaccharides, which are simple sugars with different molecular arrangements

Why are these carbohydrate structures different?

4 hours following the meal

How many hours following the meal would be little to no metabolic rate from any of these macromolecules?

2 hours following the meal

How many hours is the basal metabolic rate of the lipids at the highest?

1 hours following the meal.

When does the basal metabolic rate of the carbohydrates seem to be declining?

An abnormal mass or lump of the tissue

What is a tumor?

Form by rapid genetic mutation

How are Tumors formed?

They bind to enzymes to decrease their activity

How does an enzyme inhibitor work?

It allows the growth, repair, and maintenance of cells

Why is mitosis such an important process?

The beginning of Mitosis.

What is prophase?

Nuclear envelope breaks down, and spindle fibers form

What happens during Prophase?

Chromosomes align at the cell’s equator, and the spindle fibers attach to the centronomes of the sister cells

What happens during Metaphase?

Centronomes split, spindle fibers shape and pull the separated chromatin to the end of the cell

What happens during Anaphase?

Near end of mitosis. New nuclear envelope forms.

What happens during Telophase?

The end of Mitosis

What is Cytokinesis?

Cells are separated and the cycle repeats.

What happens during Cytokinesis?
