Midterm Review
Test Description: Midterm Review - cells, organelles, macromolecules, cell division, enzymes, and Punnett squares
Instructions: Answer all questions to get your test result.
1) How do enzymes speed up chemical reactions?
A
lowering the activation energy
B
increasing the pH
C
raising the temperature of the environment
D
creating more substrates
2) When a piece of liver is dropped into hydrogen peroxide, bubbles are released from the liver as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2). This rapid change in reaction rate suggests
A
the liver contains an enzyme that breaks down hydrogen peroxide
B
that liver is a substrate for hydrogen peroxide
C
that liver contains lots of germs
D
that hydrogen peroxide is a powerful enzyme
3) Cells must produce many different enzymes because
A
enzymes are not very effective at speeding up reactions
B
most cellular reactions require a specific, unique enzyme
C
they have to have some way to use up the protein that they consume
D
enzymes are quickly used up
4) When a piece of liver is dropped into hydrogen peroxide, bubbles are released as the hydrogen peroxide (H2O2) decomposes into water (H2O) and oxygen (O2). However, if the liver is cooked first, the reaction fails to occur. The reason for this is
A
heating kills the germs that cause the bubbling
B
heating damages the enzyme's active site in liver that breaks down hydrogen peroxide
C
heating removes the water and oxygen from the liver
D
reactions take place faster at lower temperatures
5) Crossing over occurs in the phase ______________ of ____________.
A
metaphase 2, mitosis
B
prophase 1, meiosis
C
G1, interphase
D
anaphase, mitosis
6) If there are 78 chromosomes in a dog's bone cell, then how many chromosomes will it have in its gamete?
A

C
24
D

7) What is the correct order of phases of the cell cycle (for a somatic cell)?
A
G1, S, and G2
B
interphase, prophase, metaphase, anaphase, telophase, and cytokinesis
C
prophase, metaphase, anaphase, and telophase
D
interphase, meiosis 1, meiosis 2, and cytokinesis
8) What is the first phase of mitosis?
A
prophase
B
cytokinesis
C
interphase
D
metaphase
9) How many cells are produced at the end of meiosis?
A
2 genetically different cells
B
4 genetically different cells
C
2 genetically identical cells
D
4 genetically identical cells
10) The cell membrane is made up of mostly which macromolecule?
A
nucleic acid
B
carbohydrate
C
lipid
D
protein
11) In biology what does organic mean?
A
substances that are found in the natural world
B
molecules that contain carbon
C
water molecules
D
substances that are not made of chemicals
12) Which marcomolecules are organic?
A
carbohydrates, protein, and lipids
B
carbohydrates and lipids
C
carbohydrates, proteins, lipids, and nucleic acids
D
nucleic acid
13) Under a microscope a cell is observed to have mitochondria, ribosome, nucleus, and a cell wall. What type of cell is observed?
A
a prokaryotic cell that is in bacteria
B
a eukaryotic cell that is in a plant
C
a eukaryotic cell that is in an animal
D
a eukaryotic cell in either a plant or animal
14) Which cell reproduces more quickly?
A
prokaryotic cell
B
animal cell
C
plant cell
D
eukaryotic cell
15) If a cell is damaged during interphase and it does not repair itself or go through apoptosis, then the cell will grow uncontrollably. This uncontrollable growth of cells is called ______________
A
cancer
B
mitosis
C
G2
D
cell death

A
TT and Tt
B
Tall stems and short stems
C
Tt only
D
TT, Tt, and tt
17) Round seeds (R) are dominant to wrinkled seeds. What would the parents' genotypes be if they produce offspring that are 50% round seed and 50% wrinkled seed?
A
Rr and Rr
B
Rr and rr
C
