Study Questions

In today's lesson we looked at how the cell performs the following basic functions
The cell
1.   takes in nutrients
2.  generates energy through cell respiration
3.  protects itself from harm

Nutrient intake is by diffusion -  These are glucose, amino acids, lipids, minerals and water

The cell's principal source of energy is ATP or Adenosine triphosphate.  This molecule is used up every time anything inside the cell moves.  When the molecule is used, it turns into ADP or Adenosine diphosphate.

An example of a pancreatic cell undergoing cell processes

A pancreatic cell takes in nutrients.
It's DNA provides the recipe for Insulin
Ribosomes read the recipe in the form of RNA and make Insulin
The cell exports insulin

The energy in the pancreatic cell happens in the mitochondria
The mitochondria takes in oxygen and glucose and makes carbon dioxide and water.
ADP goes to the mitochondria to transform into ATP.

ATP helps everything in that cell move.

1. Why is the mitochondria so important?
2.  What is the equation for cellular respiration?
3.  What does ADP stand for?
4  What is ATP?
5.  How does ADP turn into ATP?
6.  What types of nutrients do cells take in?
7.  In a mammal, what part of the pancreatic cell
a. provides the recipe for insulin?
b.  makes the insulin?
c.  makes the energy for making insulin?
