lesson 11
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?
