SK Cell Processes

This diagram shows cells in various stages of the cell cycle. Which stage will occur immediately after prophase? (1.2.2)

4

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane? (4.2.2)

ATP is being rapidly consumed near the cellular membrane.

Which distinguishes anaerobic respiration from aerobic respiration? (4.2.1)

Anaerobic respiration produces little ATP, while aerobic respiration produces large quantities of ATP.

Which explains why cell-to-cell communication is necessary within multicellular living things? (1.1.3)

Cells must coordinate their activities to ensure the survival of the whole organism.

Use the diagram below to answer the following question. Which process is represented by the diagram above? (1.1.3)

Chemical signaling

Which best explains the relationship between chloroplasts and mitochondria? (1.1.1)

Chloroplasts store energy in the chemical bonds of glucose, which is used by the mitochondria to produce ATP.

A red blood cell is placed in a beaker containing distilled water. What will most likely happen to the cell? (1.2.1)

It will swell.

When placed into a solution that is 30% water and 70% salt, what would happen to a cell that has a 70% water concentration? (1.2.1)

The cell will lose water and shrink to reach equilibrium with the environment.

Which would most likely happen if a cell undergoes mitosis, but not cytokinesis? (1.2.2)

The cell would have two nuclei.

A plant is placed in a sealed container. All carbon dioxide is removed from the container. Which will most likely occur? (4.2.1)

The rate of photosynthesis will decrease.

How are nerve cells adapted to perform their primary function? (1.1.3)

They are long and have branches that allow them to connect to other cells.

When a cell divides by mitosis, what will be the genetic composition of the resulting two cells? (1.2.2)

They will be identical.

Which process(es) converts stored energy into usable energy? (4.2.1)

both aerobic cellular respiration and fermentation

What are the products of aerobic cellular respiration? (4.2.1)

carbon dioxide, water, and energy

What is the ultimate cause for the difference between muscle and nerve cells? (1.1.3)

different genes are activated in the cells

What is the end result of diffusion of a solute across a cell's membrane? (1.2.1)

equal concentrations of the solute on both the inside and outside of the cell, with no net movement of the solute

In multicellular organisms, which purpose does mitosis serve? (1.2.2)

growth and development

Which explains how buffers help cells to maintain homeostasis? (1.2.1)

help keep the pH within a cell constant

During which phase of the cell cycle is the cell growing and preparing for cellular division? (1.2.2)

interphase

A cell is in need of molecules located outside of the cell. The molecules are too large and cannot pass through the membrane. What will the cell most likely do in order to get what it needs? (4.2.2)

maintain homeostasis using active transport

Which process most likely requires ATP? (4.2.2)

movement of proteins through the cell membrane

Which is necessary in order for an organism to maintain homeostasis? (4.2.2)

producing energy

What structures within the plasma membrane allow the passage of ions or large molecules? (1.2.1)

protein channels

Which cell types can differentiate into a variety of cells? (1.1.3)

stem cells

Why is it important to rid the cell of toxins? (4.2.2)

to maintain homeostasis
