Proteins are typically large molecules with multiple levels of structure. Which of the following is considered a protein's "primary structure"? |
The order of amino acids in the peptide chain. |
|
|
What determines the order of amino acids in a peptide chain? |
The DNA of the cell. |
|
|
Saturated fats, like those found in butter, are? |
Denser than oils. |
|
|
DNA is composed of nucleotide units, of which there are _____________ types. |

|
|
You eat a chocolate chip cookies. Only some of the energy in the cookies ends up as ATP (or fat). Where did the rest go? |
it leaves the body as heat. |
|
|
What type of energy is stored in a glucose molecule? |
Chemical |
|
|
What type of energy is stored in an ATP molecule? |
Chemical |
|
|
How does ATP "work" in a cell? |
It donates a phosphate group to molecules, which energizes them. |
|
|
What can happen to light when it hits a surface? |
It can be absorbed, reflected, or transmitted. |
|
|
Chlorophyll _________________ all wavelenghts except for green. |
absorbs |
|
|
What part of chlorophyll actually absorbs the light energy? |
the electrons of the molecule |
|
|
When electrons gain energy, they: |
move further away from the nucleus. |
|
|
In what way is an electron transport system like a flight of stairs? |
electrons move through the ETS like a ball dropping down each step in a flight of stairs. |
|
|
The light reactions of photosynthesis do a major energy conversion, which is light photons to |
the chemical energy of ATP and NAPDH |
|
|
What is the stored energy of the ATP and NADPH made in the light reactions used for? |
providing energy to make glucose from CO2 |
|
|
Why do plants make glucose through photosynthesis, then break it down again in cellular respiration? |
because glucose is a stable way to store energy that can later be used to generate ATP. |
|
|
Chloroplasts convert light energy into food molecules, and mitochondria convert food molecules into? |
ATP |
|
|
Which of the following is the correct pathway of energy extracted from food molecules in cellular respiration? |
Food turns into NADH and FADH2 which turns into ATP. |
|
|
Which part of cellular respiration can occur without oxygen? |
glycolysis |
|
|
Why is photosynthesis good? |
It gives us food and oxygen |
|
|
Why is cellular respiration good? |
It allows cells to slowly extract useful energy from food molecules to make ATP. |
