A cyclist rides her bike up a very steep hill. Which choice below properly describes this example in energetic terms? Both a) and d) are correct.
Every time a source of energy is converted from one form to another: some of the energy is converted to heat, which is not a very usable form of kinetic energy.
A green plant will grow if given nothing more than: water, light, and carbon dioxide
The leaves of plants can be thought of as "eating" sunlight. From an energetic perspective this makes sense because light energy, like the chemical energy stored in food molecules, is used inside plants to do work.
Mitochondria have a "bag within a bag" structure. This is necessary to: create two distinct regions with a concentration gradient between them, a form of potential energy.
During the Krebs cycle: the products of glycolysis are further broken down, generating additional ATP and the high-energy electron carrier NADH
A molecule of chlorophyll increases in potential energy: when one of its electrons is boosted to a higher-energy excited state upon being struck by a photon of light
During C4 photosynthesis: plants are able to continue producing sugars even when they must almost completely close their stomata to reduce water loss during hot days.
Which of the following energy-generating processes is the only one that occurs in all living organisms: glycolysis
In your body, when energy is released from the breakdown of a molecule such as glucose: some of it may be harnessed by building the unstable high-energy bonds that attach phosphate groups to ADP
The actual production of sugars during photosynthesis takes place within the stroma, outside of the thylakoid, but still inside the chloroplast
During photosynthesis, which step is most responsible for a plant's acquisition of new organic material the "plucking" of carbon molecules from the air and affixing of them to organic molecules within the chloroplast.
In harvesting the chemical energy...
