Question 1: What happens as energy is converted from one form to another

Answer:

there is always a loss of usable energy. The energy that is "LOST" is generally lost as heat Question 2: How does energy stored in the glucose produced by photosynthesis get transferred to other organisms

Answer:

energy can be transferred to other organisms when the molecules are consumed as food

Question 3: What does ATP stand for

Answer:

Adenosine Triphosphate

Question 4: What happens when ATP loses a phosphate

Answer:

it releases energy for the cells to use

Question 5: Name four forms of energy... remember that energy can be converted to other forms of energy)

Answer:

light energy, mechanical energy, thermal energy, chemical energy Question 6: What two metabolic pathways work together and allow energy to continually flow between organisms in an ecosystem

Answer:

photosynthesis and cellular respiration

Question 7: During cellular respiration, what energy transformation occurs

Answer:

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 Question 8: What molecule provides chemical energy that powers cellular activities in organisms

Answer:

ATP ( glucose needs to be converted to ATP in order for the cells to have energy) Question 9: What is true about reactants and products of photosynthesis and cellular respiration

Answer:

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 ) Question 10: What does photosynthesis produce that is USED by aerobic cellular respiration

Answer:

glucose and oxygen Question 11: During photosynthesis energy is not created from sun... but what energy transformation occurs

Answer:

energy is converted from light energy to chemical energy in the form of glucose

Question 12: review// what is metabolism

Answer:

all the chemical rections in an organism..

Question 13: what is a heterotroph

Answer:

organisms need to ingest food to obtain energy (eat other organisms)

Question 14: What is true about ATP and ADP (it makes a cycle)

Answer:

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)

Question 15: What are two types of autotrophs/// describe each

Answer:

chemoautotrophs ( use inorganic substances such as hydrogen sulfide as a source of energy)...photoautotrophs convert light energy into chemical energy...

Question 16: Describe the basic process of cellular respiration? purpose

Answer:

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) Question 17: True or False.... Both ATP and ADP can provide energy for organisms

Answer:

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

Question 18: Directly or indirectly nearly all the energy for life comes from

Answer:

THE SUN

Question 19: What is chemical energy

Answer:

energy stored in chemical molecules ( it is energy in the bonds... when the bonds are broken the energy is released)

Question 20: What happens in the metabolic pathway known as photosynthesis

Answer:

light energy is converted to chemical energy that is stored for later use by the cell Question 21: True or False.... ATP is the only molecule that provides energy for cells....

Answer:

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 Question 22: Give an example of an energy conversion in an animal.... what happens when you eat food and run

Answer:

the chemical energy in food is converted to mechanical energy when muscles contract

Question 23: How does ATP release energy

Answer:

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...

Question 24: What is the law of conservation of energy

Answer:

energy cannot be created or destroyed but can be converted from one form to another

Question 25: What happens when ADP gains a phosphate

Answer:

it stores energy and becomes ATP
