• Golgi Apparatus

Multiple Choice

Which of the following describes the role that enzymes play in the process of metabolism?

• Enzymes carry the genetic instructions required for a cell to initiate metabolism.

• Enzymes increase the rate of the chemical reactions carried out during metabolism.

• Enzymes provide the chemical energy that is broken down and released during metabolism.

• Enzymes store the chemical energy that is used to construct nucleic acids during metabolism.

Multiple Choice

Why has this enzyme activity decreased so much?

• The enzyme has become saturated

• The temperature is too low

• The enzyme has become denatured

Multiple Choice

What does it mean to say that a cell membrane is semipermeable?

• it allows some materials to pass through

• it allows nothing to enter the cell, only to leave

• It only allows things into the cell and not out

• it allows all materials to pass through

Multiple Choice

Which cell is placed into a hypotonic environment? 

• A
• B
• C
• D

Multiple Choice

Which way will water move?

• into the cell

• out of the cell

• in and out of the cell at an equal rate

Multiple Choice

Use the diagram to answer the following question. The diagram shows the movement of ions against a concentration gradient to an area of higher concentration. Which molecule provides the energy needed for this movement to occur in a cell?

• ATP

• mRNA

• protein

• lipid

Multiple Choice

Which statement best describes the role of ATP in a living system?

• ATP senses and adjusts the pH in the cellular environment.

• ATP identifies and repairs weak components of cells and tissues.

• ATP measures and provides heat to increase reaction rates in cells.

• ATP captures and transfers energy released by the breakdown of glucose.

Multiple Choice

Letter A represents which molecule?

• water

• oxygen

• glucose

• ATP

Multiple Choice

Letter B represents what molecule?

• water

• oxygen

• glucose

• ATP

Multiple Choice

Which statement best explains why cellular respiration in plants and other organisms is dependent on photosynthesis?

• Photosynthesis is one of the final steps in cellular respiration.

• Photosynthesis provides the materials that fuel cellular respiration.

• Photosynthesis absorbs excess energy produced by cellular respiration.

• Photosynthesis absorbs materials that are catalyzed during cellular respiration.

Multiple Choice

What type of RNA carries the DNA message out of the nucleus to the ribosomes?

• mRNA
• tRNA
• RNA
• DNA

Multiple Choice

_______ is made during transcription and ________ is made during translation.

• mRNA / a protein
• a protein / mRNA
• Ribosome / Nucleus
• mRNA / tRNA

Multiple Choice

The image shows the production of petal color in a flower. What can be concluded from the diagram?

• DNA and a protein mix together to produce purple flowers.

• Proteins stop the DNA from keeping the flower petals white.

• DNA codes for a protein that makes pigments so the flower appears purple.

• A pigment protein makes DNA, which causes the flower to appear purple.

Multiple Choice

Which process and type of resulting cells are represented in the diagram?

• meiosis, which produces body cells.

• mitosis, which produces gametes

• meiosis, which produces gametes

• mitosis, which produces body cells

Multiple Choice

The genetic event shown in the diagram can occur during meiosis. Which statement best describes this type of event?

•   Gene sequences that are identical are replicated and added to the homologous chromosome.

• Sections of DNA between nonhomologous chromosomes are exchanged, decreasing genetic diversity.

•   Segments of homologous chromosomes are exchanged, resulting in cells that will be genetically different.

•   The traits from two sections of the same DNA strand are altered, resulting in the production of a new species.

Dropdown

We all have two alleles, or versions, of each gene. Being ​

Select answer

for a particular gene means you inherited two identical versions. It's the opposite of a ​

Select answer
