Resource summary

Question 1

Question
What is a Metabolic pathway?
Answer
  • Metabolic energy that is captured more easily if it is released in large amounts rather than in small
  • A series of steps (in cells) in which molecules are broken down OR assembled
  • substrates fit onto the enzyme in such a way that they are oriented to react.

Question 2

Question
Enzymes catalyze (speed up) reactions in metabolic pathways
Answer
  • True
  • False

Question 3

Question
Energy transformations are always 100% efficient.
Answer
  • True
  • False

Question 4

Question
Organisms are open systems (constant energy in-flow).
Answer
  • True
  • False

Question 5

Question
Shape determines protein function. Enzymes are proteins.
Answer
  • True
  • False

Question 6

Question
Substrate molecules bind to Enzymes active sites
Answer
  • True
  • False

Question 7

Question
What is chemical energy responsible for?
Answer
  • Chemical energy determines how active certain chemicals in your bloodstream are
  • Providing living cells with energy from food
  • Providing the energy the body needs to regulate the amount of chemicals in the body.
  • All of the above

Question 8

Question
What is encode?
Answer
  • one must attend
  • one must review
  • one must rehearse

Question 10

Question
Which of the following is NOT a component of the Unified Cell Theory?
Answer
  • All living things are composed of one or more cells
  • All new cells arise from existing cells
  • A network of protein fibers that maintain the shape of the cell
  • The cell is basic unit of life (the smallest entity that can be “living”)

Question 11

Question
Which of the following is NOT a component of Plasma Membrane
Answer
  • Cholesterol
  • Proteins
  • Carbohydrates
  • Ribosomes
  • Phospholipids

Question 12

Question
Which of the following does not stand true for Membrane Functions and molecules that perform functions:
Answer
  • Carbohydrates→ “identification tags” showing type of cell and whether it belongs in organism
  • Proteins→ “doors” and “pumps” for transporting molecules in or out of the cell
  • Cholesterol→ gives stability to fluid membrane of animal cells and responds to temperature conditions in the cell’s environment
  • Ribosomes→ a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cell
  • Osmosis→ diffusion of water molecules across a permeable membrane
  • Flows from high to low→ molecules, from high to low concentration

Question 13

Question
Which of the following does NOT require energy?
Answer
  • Sugars flowing through protein channels from high blood levels to low levels in brain cells
  • Movement of sodium ions from low concentration outside a cell to higher concentration inside a cell
  • Moving fat or lipid molecules from low concentration in the blood to high concentration in fat storage cells

Question 14

Question
Which of the following DOES require energy?
Answer
  • Flow of oxygen-rich red bloods cells, to oxygen-starved muscle cells during exercise
  • Diffusion of water or gases through the membrane.
  • Moving fat or lipid molecules from low concentration in the blood to high concentration in fat storage cells

Question 15

Question
-In all the cases below, blood sugar (glucose) is flowing into a cell, through a channel protein in the cell membrane. In which case will the flow of sugar be fastest?
Answer
  • Sugar concentration outside the cell: 10%. Sugar concentration inside the cell: 3%
  • Sugar concentration outside the cell: 6%. Sugar concentration inside the cell: 3%
  • Sugar concentration outside the cell: 10%. Sugar concentration inside the cell: 9%
