In the presence of oxygen, glycolysis is followed by
the krebs cycle
100
Breathing heavily after running a race is your body’s way of
repaying an oxygen debt.
100
As a cell becomes larger, its
volume increases faster than its surface area.
100
The process by which a cell divides into two daughter cells is called
cell division.
100
During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
Centrioles duplicate.
200
Cellular respiration uses 1 molecule of glucose to produce approximately how many ATP molecules?
38
200
The energy needed to win a 1-minute footrace is produced mostly by
lactic acid fermentation.
200
If the surface area of a cell that is shaped like a cube increases 100 times, its volume increases about
1000 times
200
During which phase in the cell cycle does mitosis happen?
m phase
200
What is the role of the spindle fibers during mitosis?
They help separate the chromosomes.
300
The starting molecule for the Krebs cycle is
pyruvic acid.
300
When microorganisms in milk produce acid under certain conditions, yogurt results. Which of these processes would you expect to be key in the production of yogurt?
lactic acid fermentation
300
What is a problem that growth causes for cells
obtaining enough food or more demands on DNA or expelling wastes
300
An advantage of sexual reproduction over asexual reproduction is that sexual reproduction
provides genetic diversity
300
During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
metaphase
400
The Krebs cycle produces
Carbon Dioxide
400
The conversion of pyruvic acid into lactic acid requires
NADH
400
The rate at which wastes are produced by a cell partially depends on the cell’s
volume
400
When during the cell cycle are chromosomes visible?
only during cell division
400
During normal mitotic cell division, a parent cell that has four chromosomes will produce two daughter cells, each containing
4 chromosomes
500
In eukaryotes, electron transport occurs in the
inner mitochondrial membrane
500
During fermentation what happens?
NAD+ is regenerated, allowing glycolysis to continue.
500
What happens when a cell divides?
Each daughter cell receives its own copy of the parent cell’s DNA
