Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
- The <u>food </u>we eat
- The <u>environment </u>we expose the cell to
- The <u>substances </u>that touch the cell (e.g skin cells)
That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of <u>programmed cell death</u>.
<u>Programmed cell death </u>is what tells a cell when it should stop growing and dividing. This is a <u>regulatory function </u>designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The <u>accumulation </u>of these cells is referred to as cancer.

The answer is D. i past this class with a 98 overall score.
Answer: B) ATP to ADP
This reaction is termed as ATP hydrolysis.
ATP ( adenosine triphosphate) conversion to ADP ( adenosine diphosphate) is an energy producing reaction ( exothermic reaction). ATP contains high energy bonds called phosphoanhydride bonds. Thus, when this bond is broken down, ATP is converted to ADP and Pi ( inorganic phosphate) and releases large amount of energy.
The female flowers mature before the male flowers, resulting in self-fertilization being preventing
Best Answer:
ATP synthase makes ATP. found in the inner mitochondrial membrane, it
uses the energy of the proton electrochemical gradient produced by the
electron transport chain to make atp from adp and inorganic phosphate.
the enzyme itself has a passage for protons, and a head which turns. The
head has 3 idential components. passing 10 protons through will turn
the head once. ADP and phosphate can bind to one of the 3 components and
the turning will cause the component to essentially sequeeze the ADP
and phosphate together to make ATP.
