|---|---|---|---|---|---|
| What is the law of conservation of energy | show 🗑
|
||||
| During photosynthesis energy is not created from sun... but what energy transformation occurs | show 🗑
|
||||
| During cellular respiration, what energy transformation occurs | show 🗑
|
||||
| What happens as energy is converted from one form to another | show 🗑
|
||||
| show | THE SUN
🗑
|
||||
| What are the organisms that make their own food to use as energy | show 🗑
|
||||
| show | chemoautotrophs ( use inorganic substances such as hydrogen sulfide as a source of energy)... photoautotrophs convert light energy into chemical energy...
🗑
|
||||
| show | organisms need to ingest food to obtain energy (eat other organisms)
🗑
|
||||
| review// what is metabolism | show 🗑
|
||||
| show | 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
🗑
|
||||
| show | 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 | show 🗑
|
||||
| show | energy can be transferred to other organisms when the molecules are consumed as food
🗑
|
||||
| show | 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 )
🗑
|
||||
| show | Photosynthesis stores energy.... Cellular Respiration releases energy
🗑
|
||||
| show | 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 | show 🗑
|
||||
| What does cellular respiration produce that is USED by photosynthesis | show 🗑
|
||||
| show | Adenosine Triphosphate
🗑
|
||||
| show | energy stored in chemical molecules ( it is energy in the bonds... when the bonds are broken the energy is released)
🗑
|
||||
| show | light energy, mechanical energy, thermal energy, chemical energy
🗑
|
||||
| show | the chemical energy in food is converted to mechanical energy when muscles contract
🗑
|
||||
| show | 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.... | show 🗑
|
||||
| show | 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 | show 🗑
|
||||
| show | 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 | show 🗑
|
||||
| show | it releases energy for the cells to use
🗑
|
||||
| What happens when ADP gains a phosphate | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
