Atoms & Molecules
What is the smallest unit of an element that retains its chemical properties?
An Atom
Which macromolecule provides a common source of quick energy?
Which process uses light energy to produce glucose?
Photosynthesis
What process changes water vapor into water vapor?
Evaporation
What is homeostasis
any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival.
What are the 3 main subatomic particles?
Protons, Neutrons, and electrons
What are the monomers that make up proteins?
Amino Acids
What organelle carries out cellular respiration in eukaryotic cells?
Mitochondria
What process removes carbon dioxide from the atmosphere and incorporates its carbon into sugars?
Photosynthesis
How does sweating help maintain homeostasis?
Sweating cools the body when temperature rises.
________ are the small, repeating units that make up larger molecules called polymers
Monomers
Which macromolecule includes DNA and RNA?
Nucleic acids
What are the 3 reactants of photosynthesis?
CO2, H2O, and Light energy
What are the 2 processes that release CO2 into the air?
respiration, combustion
What enzyme breaks down lactose, the sugar found in milk?
Lactase
Why can carbon from so many different biological molecules?
Carbon has 4 valence electrons and can form 4 covalent bonds
What is the function of Lipids?
Long-term energy storage and cell membrane support
What is the main purpose of cellular respiration?
to convert glucose into ATP, the molecule your cells use as energy for virtually everything they do.
In the carbon cycle, in which sphere does decomposition take place?
Geosphere
Give one example of homeostasis.
Regulation of body temperature through sweating or shivering.
What biochemical pocess breaks down a polymer into a monomer?
Dehydration Synthesis
What elements(atoms) are in nucleic acids?
C, H, O, N, and P
How are photosynthesis and cellular respiration connected?
Photosynthesis stores energy in glucose and releases oxygen. Cellular respiration uses glucose and oxygen to release usable energy, producing carbon dioxide and water
A forest loses most of its trees. Predict how this could affect the carbon cycle.
Less photosynthesis would occur, which means less atmospheric CO2 would be absorbed
Lactose intolerance occurs when a person cannot digest lactose properly because of low lactase activity. Lactase persistence is continued lactase production into adulthood
