Energy and ATP

How organisms obtain energy ... How ATP works

QuestionAnswer
What is the law of conservation of energy energy cannot be created or destroyed but can be converted from one form to another
During photosynthesis energy is not created from sun... but what energy transformation occurs energy is converted from light energy to chemical energy in the form of glucose
During cellular respiration, what energy transformation occurs energy is converted from one form of chemical energy ( in chemical bonds of glucose) to another form of chemical energy ( in the chemical bonds of ATP)... this conversion takes place in order to make a form of energy that the cells can use
What happens as energy is converted from one form to another there is always a loss of usable energy. The energy that is "LOST" is generally lost as heat
Directly or indirectly nearly all the energy for life comes from THE SUN
What are the organisms that make their own food to use as energy Autotrophs
What are two types of autotrophs/// describe each chemoautotrophs ( use inorganic substances such as hydrogen sulfide as a source of energy)... photoautotrophs convert light energy into chemical energy...
what is a heterotroph organisms need to ingest food to obtain energy (eat other organisms)
review// what is metabolism all the chemical rections in an organism..
What happens in the metabolic pathway known as cellular respiration cellular respiration is a metabolic pathway that release energy by breaking down larger molecules into smaller molecules ( in cellular respiration.... glucose is broken down to carbon dioxide and water...releasing energy
What happens in the metabolic pathway known as photosynthesis light energy is converted to chemical energy that is stored for later use by the cell
What two metabolic pathways work together and allow energy to continually flow between organisms in an ecosystem photosynthesis and cellular respiration
How does energy stored in the glucose produced by photosynthesis get transferred to other organisms energy can be transferred to other organisms when the molecules are consumed as food
What is true about reactants and products of photosynthesis and cellular respiration the products of one reaction are the reactants for the other reaction... Photosythesis makes glucose and oxygen which are used by cellular respiration to make ATP , carbon dioxide and water( which are again used during photosynthesis )
Which metabolic process STORES ENERGY,,, Which RELEASES ENERGY and together they allow energy to flow continuously in the biosphere Photosynthesis stores energy.... Cellular Respiration releases energy
Describe the basic process of cellular respiration? purpose Cellular respiration is a metabolic process that breaks down larger molecules to release energy.... Organic molecules ( glucose is a good example) is broken down to release energy for use by cell ( it releases energy to make ATP)
What does photosynthesis produce that is USED by aerobic cellular respiration glucose and oxygen
What does cellular respiration produce that is USED by photosynthesis carbon dioxide and water... ( these are the small waste products of cellular respiration)
What does ATP stand for Adenosine Triphosphate
What is chemical energy energy stored in chemical molecules ( it is energy in the bonds... when the bonds are broken the energy is released)
Name four forms of energy... remember that energy can be converted to other forms of energy) light energy, mechanical energy, thermal energy, chemical energy
Give an example of an energy conversion in an animal.... what happens when you eat food and run the chemical energy in food is converted to mechanical energy when muscles contract
What molecule provides chemical energy that powers cellular activities in organisms ATP ( glucose needs to be converted to ATP in order for the cells to have energy)
True or False.... ATP is the only molecule that provides energy for cells.... FALSE... there are other carrier molecules that transport energy BUT ATP is the most abundant energy-carrier molecule in cells and is found in all types of organisms
Review: Which biomolecule is ATP related to and explain ATP is related to nucleic acids... it is a modified nucleotide... most nucleotides have a nitrogen base, a sugar and a phosphate..ATP has a tail of 3 phosphates (adenosine TRIPHOSPHATE)
How does ATP release energy ATP releases energy when the bond between the second and third phosphate groups is broken( break off 3rd phosphate)... this forms adenosine diphosphate (ADP) and a free phosphate that joins to other molecules to energize them...
What is true about ATP and ADP (it makes a cycle) ATP and ADP can be interchanged by the addition or removal of a phosphate group ... ATP minus a P makes ADP... (which still has energy)... and ADP plus a P makes ATP (most energy)
True or False.... Both ATP and ADP can provide energy for organisms TRUE... most of the energy reactions in a cell involve ATP and ADP.... there is an AMP but it really doesn't have much energy
What happens when ATP loses a phosphate it releases energy for the cells to use
What happens when ADP gains a phosphate it stores energy and becomes ATP

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
