BIOL 1013 Exam 2 Study Guide latest
1. What are autotrophs?: Organisms such as plants, algae, and certain
bacteria that can make food from inorganic (nonliving) starting materials
2. What are heterotrophs?: Organisms that can't make their own food and
must consume organic molecules produced by other living organisms to obtain
energy
3. What is energy?: The ability to do work. Living organisms obtain energy either
directly from sunlight (through photosynthesis) or from food they consume.
4. What is potential energy?: Stored energy.
5. What is kinetic energy?: The energy of motion or movement.
6. What is chemical energy?: Potential energy stored in the bonds of biological
molecules.
7. What happens during energy transformation?: Converted from one form to
another and heat is lost to the surrounding environment. (Sometimes not
efficient)
8. What is chlorophyll?: (Pigment molecule, captures the energy from the sun.
Utilized for light reaction to take place)The pigment present in the green parts of
plants that absorbs photons of light energy during the "photo" reactions of
photosynthesis.
9. What color does chlorophyll reflect?: Green
10. What color does chlorophyll absorb?: Other colors around it, such as red &
blue
11. What is the equation for photosynthesis?:
12. What occurs during photosynthesis?: During the "photo" step, light energy
is captured in chemical form. In the process, water is split and oxygen is
released as a by-product. During the "synthesis" step, this chemical energy
powers the formation of glucose molecules, using the carbon atoms of carbon
dioxide.
13. What is body mass index (BMI)?: An estimate of body fat based on height
and weight.
14. What is a calorie?: The amount of energy required to raise the temperature
of 1 g of water by 1°C
15. What is ADP?: Molecule that ATP becomes when it gives up one of its three
phosphate groups.
16. What is ATP?: The molecule in cells that powers energy-requiring functions.
17. What occurs during aerobic respiration?: A series of reactions that occurs
in the presence of oxygen and converts energy stored in food into ATP.
