Which of the following statements is true regarding the flow of energy from the sun to stored chemical energy?
- Energy is recycled in biological systems
- As energy flows in a biological system, some energy is lost in the form of heat
- Energy flows in biological systems with no loss of usable energy when it is transformed
- Plants create energy and animals get energy from plants
How does the energy content of ATP and ADP differ?
- ATP is a higher energy molecule than ADP.
- ADP is a higher energy molecule than ATP
- ATP and ADP contain the same amount of energy
Where is the chemical energy of ATP mainly stored?
- In the bond between the ribose and the first phosphate.
- In the bond between the first two phosphates.
- In the bonds of the adenine base.
- In the bond between the last two phosphates.
- In the bonds of the ribose.
If a reaction or other process releases energy, then reversing the process will…
- also release energy
- require energy
- not be possible
How does growth work?
- To grow, a cell must do both catabolic and anabolic reactions. Organic food molecules are not complex enough to be used for growth. Therefore anabolic and catabolic reactions must be done to make the molecular structure more complex.
- To grow, a cell must only do anabolic reactions. Simpler food molecules are taken in and strung together to make more complex molecules of the cell.
- To grow, a cell must simply take in complex organic molecules and store them. You are exactly what you eat.
- To grow, a cell must do both catabolic and anabolic reactions. Food molecules must be partly broken down and then rebuilt in new forms to enable growth; you aren’t exactly what you eat.
Energy from the sun can be captured by living organisms and stored in the form of :
Animals create energy by converting glucose to ATP during cellular respiration: true or false?
Is the process of converting an 18-carbon fatty acid chain into nine two-carbon molecules an example of a catabolic or anabolic process?
Is the production of fatty acids catabolic or anabolic?
Select whether ‘forming a peptide bond between amino acids to make protein’ is an example of a catabolic or anabolic process.
ATP is formed from ADP by the addition of _____ to ADP.
- sodium ions
Energy is released when
- ATP is converted to ADP and Pi.
- ADP and Pi are joined to form ATP.
Points: 10 out of 10
Which of the following options best describes how energy flows through a consumer?
- ATP → anabolic reactions → organic molecules → catabolic reactions → anabolic reactions and other cellular work
- organic molecules → anabolic reactions → ATP → catabolic reactions
- organic molecules → catabolic reactions → ATP → anabolic reactions and other cellular work
- inorganic molecules → ATP → organic molecules → anabolic reactions and other cellular work
True or False: The hydrolysis of AMP (adenosine monophosphate) will release similar amount of energy as the hydrolysis of ATP or ADP.
Which of the following is NOT a type of energy?
- Chemical energy
Select whether the splitting of disaccharide sucrose (table sugar) into its components (fructose and glucose) is an example of a catabolic or anabolic process:
Energy is defined as:
- The ability to jump around.
- The ability to do work.
- The ability to increase the temperature of something.
A compound that is widely used to provide energy to anabolic pathways is:
When ADP is converted to ATP, the new phosphate is added to which position on the molecule?
Plants create energy when they convert CO2 to glucose: true or false?
