Chapter 1 & 2
The living creation and its chemistry
The living creation and its chemistry
Biology is the study of this.
What is life?
Modern cell theory
What is all living things are made of cells, all cells come only from preexisting cells, and cels perform the functions of living things.
There is too much energy in this molecule for cells to use directly, and it is broken down into smaller "energy currency."
What is glucose?
Water molecules molecules split, ATP synthase makes ATP from ADP, and energized electrons pass through the electron transport chain during this phase of photosynthesis.
What is the light-dependent phase?
Nucleic acids such as DNA and RNA store this.
What is information?
The characteristics of life (name at least 3)
Cells:
Reproduction (reproduce after their own kind)
Metabolism (use energy for cellular processes)
Organization (made of organized cells)
Growth (grow and develop)
Response (homeostasis - responding to the environment)
When cells and the solution surrounding them contain equal amounts of solute, the solution is said to be this.
What is isotonic?
Acids such as DNA and RNA. store this.
What is information?
These 3 things can affect the rate of photosynthesis in plants.
What is availability of water, availability of carbon dioxide, and temperature?
This is the part of a nucleotide that is different in each of the five kinds found in DNA and RNA.
What is the nitrogenous base?
Name 4 types of energy.
Accept any 4:
mechanical
acoustical
light
thermal
chemical
This happens to a cell that is exposed to a temperature outside its range of tolerance.
What is death?
This cellular organelle that reads an RNA and assembles amino acids into protein chains is called this.
What is a ribosome?
The main purpuse of the Krebs Cycle (citric acid cycle) is to produce these two things for the electron transport chain.
What is NADH and electrons?
These bonds hold the sides of the DNA "ladder" together.
What are hydrogen bonds?
Organic compounds all contain this.
What is carbon?
When a cell maintains stable conditions in response to its external environment.
What is homeostasis?
A tRNA aligns its amino acid in the proper sequence by matching this to the corresponding codon on the mRNA.
What is anticodon?
Cellular respiration is this, because it uses oxygen.
What is aerobic?
Proteins are made using the information stored here.
What is DNA?
The parts to a chemical equation.
ATP is produced in this organelle.
What is mitochondria?
The process of copying an RNA molecule from a DNA molecule.
What is transcription?
During aerobic cellular respiration, the most ATP is generated during this cycle.
What is the electron transport chain?
A triplet of nucleotide bases that corresponds to a particular amino acid is called this.
What is a codon?
