ADP + P + ENERGY --- ATP

Click on objects to label the chemical reaction which allows the cell to store chemical energy.

adenosine diphosphate

Converted into ATP during glucose breakdown

glycolysis

The first step in the chemical breakdown of glucose

solar

The ultimate source of energy for starting the food chain is:

pyruvic acid lactic acid

When oxygen is lacking, animal cells change to .

adenosine triphosphate

Which molecule has greater energy potential?

mitochondria

Which of the following organelles acts as the cell's powerplant?

ATP

The complete process which is needed to produce is called the Krebs cycle.

plastids

contain starch and oil or plant pigments

vacuoles

digest foods

6CO 2 + 12H 2 O--------CHLOROPHYLL C 6 H 12 O 6+ 6O 2 + 6H 2 O

process of photosynthesis.

lysosomes

store glucose as glycogen

mitochondria

supply the cell with energy (ATP)

needs oxygen produces more ATP than glycolysis produces carbon dioxide produces water

The Krebs Cycle:

enzyme

A molecule which serves to make reactions work

photosynthesis

A process in green plants which involves the use of the sun's energy

organelle

A small structure within the cell which serves specialized functions

carbohydrates

Cells in a person's body obtain glucose from the digestion of .

glycogen

Chain molecule made of many glucose molecules linked together

ATP --- ADP + P + ENERGY

Click on objects to label the chemical reaction which occurs within the cell when it needs energy.

C 6 H 12 O 6+ O 2 --- CO 2 + H 2 O + ENERGY

Click on the pieces of the chemical reaction to show what occurs within the mitochondrion.

starch glycogen

Glucose is one of the simple sugars in the long chain polymer, and animal cells store it is as .

vacuoles

Glucose is stored in within the cell.

fermentation

Involves the production of ethyl alcohol from glucose

adenosine triphosphate

It serves as an energy source for the cell

False

It would appear logical that the first cell could have started to function from one organelle having formed by accident.

enzymes

Lysosomes are able to help digest the food material in the vacuole because they contain that they spill into the vacuole.

lysosome

Packets within the cell cytoplasm that contain digestive enzymes

mitochondria

Structure within the cell responsible for the production of energy

organelles

Subunits within the cells that perform specific functions are called .

mitochondria

The Krebs cycle takes place within the :

pyruvic acid

The end product of glycolysis in the breakdown of glucose

intelligent design

The enormous complexity of cells supports the theory of .

release energy for making ATP

The purpose of the Krebs cycle is to:

True

The simplest operational cell is still more complex than a computer.

plants

The source of stored energy in the form of food for all animals and humans ultimately comes from:

lactic acid

The substance produced by body cells when there is not enough oxygen

plastid

Tiny sacs in the cell which may contain starch

adds a phosphate to ADP changes ADP to ATP

What is the function of the energy released by the mitochondrion?
