Biology Ch. 9-10 Quiz(AT) Flashcards
True/False: ATP contains three high energy bonds and ADP should have two high energy bonds.
False
True/False: ATP is similar to a fully charged battery and ADP is similar to a partially charged battery.
True
True/False: Your cells contain about a 24 hour “charge” of ATP molecules.
False
True/False: ATP is a great molecule for long term energy storage.
False
True/False: In order to obtain energy from food, chemical bonds must be broken in food molecules.
True
True/False: Cells break down food molecules very quickly in a single step.
False
True/False: Oxygen is the final electron acceptor in the electron transport chain.
True
True/False: Glycolysis is anaerobic and therefore does not require oxygen to run.
True
True/False: In alcoholic fermentation ethanol is produced. In lactic acid fermentation, lactic acid and carbon dioxide are produced.
False
The two forms of fermentation are __________ and ___________.
Lactic acid and alcoholic
What are the three main subunits of adenosine triphosphate?
Adenine, ribose, and 3 phosphates
Adenine triphosphate is commonly referred to as __________.
ATP
Adenosine diphosphate is very similar to adenosine triphosphate except that adenosine diphosphate contains _____ high energy bond(s) and adenosine triphosphate has ______ high energy bonds.
1, 2
The energy to power our cells comes, most directly, from _________.
food
The ultimate source of energy for almost all life on this planet is the _______.
sun
Name a specific organism that is a heterotroph.
Dog, cat, you etc.
Write the balanced equation for cellular respiration.
602 + C6H12O6 —–> 6H2O + 6CO2 + energy
What are the 3 main stages of cellular respiration?
Glycolysis, Krebs’s cycle, and electron transport chain
A cell process that occurs without oxygen is termed _________ and a cell process that occurs with oxygen is termed_______.
anaerobic and aerobic
Cellular respiration begins by energizing glucose with two ATP molecules. This energy ultimately causes the glucose molecule to be split into two-________ carbon molecules. (indicate the numbers of carbons on the molecule)
3
After the first step of glycolysis occurs, a hydrogen carrying molecule called NAD+ picks up a hydrogen ion (H+), and two very energetic ________.
electrons
After the first major step of glycolysis occurs, four molecules of ADP are charged up to make four molecules of __________.
ATP
For each molecule of glucose, the Krebs’s cycle must run how many times?
Twice
Fermentation is a biochemical pathway that occurs when _______ is unavailable.
oxygen
In order to continue producing energy under low oxygen conditions, fermentation occurs which allows NADH to be converted back to NAD. Without this alternate biochemical pathway, no energy would be produced when oxygen was unavailable and the organism and/or its cells would _________.
likely die
During periods of oxygen debt, human cells perform _________ fermentation to produce some energy.
lactic acid
