Organelles
Structure within the cell responsible for the production of energy
mitochondria
A small structure within the cell which serves specialized functions
organelle
The simplest operational cell is still more complex than a computer.
true
Glucose is stored in within the cell.
vacuoles
store glucose as glycogen
vacuoles
When oxygen is lacking, animal cells change to
pyruvic acid, lactic acid
contain starch and oil or plant pigments
plastids
The purpose of the Krebs cycle is to:
release energy for making ATP
It would appear logical that the first cell could have started to function from one organelle having formed by accident.
false
Converted into ATP during glucose breakdown
adenosine diphosphate
It serves as an energy source for the cell
adenosine triphosphate
Which molecule has greater energy potential?
adenosine triphosphate
Click on the pieces of the chemical reaction to show what occurs within the mitochondrion.
c6h12o6+o2---->co2+h2o+energy
Cells in a person's body obtain glucose from the digestion of
carbohydrates
The substance produced by body cells when there is not enough oxygen
lactic acid
digest foods
lysosomes
The Krebs Cycle:
needs oxygen produces more ATP than glycolysis produces carbon dioxide produces water
Subunits within the cells that perform specific functions are called
organelles
A process in green plants which involves the use of the sun's energy
photosynthesis
The source of stored energy in the form of food for all animals and humans ultimately comes from:
plants
Tiny sacs in the cell which may contain starch
plastid
The end product of glycolysis in the breakdown of glucose
pyruvic acid
Glucose is one of the simple sugars in the long chain polymer, and animal cells store it is as .
starch, glycogen
The Krebs cycle takes place within the :
mitochondria
Which of the following organelles acts as the cell's powerplant?
mitochondria
What is the function of the energy released by the mitochondrion?
adds a phosphate to ADP changes ADP to ATP
supply the cell with energy (ATP)
mitochondria
Packets within the cell cytoplasm that contain digestive enzymes
lysosome
A molecule which serves to make reactions work
enzyme
Click on the appropriate labels to express the process of photosynthesis.
6co2+12h2o+chlorophyll--->c6h1206+602+6h20
Click on objects to label the chemical reaction which allows the cell to store chemical energy.
ADP+ P +energy--->ATP
The complete process which is needed to produce is called the Krebs cycle.
ATP
Click on objects to label the chemical reaction which occurs within the cell when it needs energy.
ATP--->ADP+P+energy
Lysosomes are able to help digest the food material in the vacuole because they contain that they spill into the vacuole.
enzymes
Involves the production of ethyl alcohol from glucose
fermentation
Chain molecule made of many glucose molecules linked together
glycogen
The first step in the chemical breakdown of glucose
glycolysis
The enormous complexity of cells supports the theory of
intelligent design
The ultimate source of energy for starting the food chain is:
solar
