1.

What is Cellular Respiration ?

a)

The process of changing one form of energy into another

b)

A series of processes that take place within a cell where biochemical energy from organic substances (glucose) is converted into energy molecules called ATP for use in cell activities

2.

What is an Enzyme ?

a)

The energy required to start a reaction

b)

A protein that catalyzes (speeds up) a reaction without being changed by it

3.

What is Photosynthesis ?

a)

Energy for life, the high-energy molecule that stores the energy we need to do just about everything

b)

The ongoing “energy recycling,” through oxidative phosphorylation of “low energy” adenosine diphosphate (ADP) molecules, to “high energy” adenosine triphosphate (ATP) molecules (binding energy), and the subsequent hydrolysis of ATP molecules back to ADP (releasing energy)

c)

A process in which complex organic molecules are synthesized using carbon dioxide, water, and light energy (from sunlight) captured by light-absorbing pigments, such as chlorophyll

4.

What is a Substrate ?

a)

A chemical or set of chemicals that are affected by enzymes

b)

The energy required to start a reaction

5.

What is Activation Energy ?

a)

The energy required to start a reaction

b)

Energy for life, the high-energy molecule that stores the energy we need to do just about everything

c)

The process of changing one form of energy into another

6.

What is ADP-ATP Cycling ?

a)

A sequence of reactions in organisms in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds (as in ATP). Also called the Krebs cycle

b)

The ongoing “energy recycling,” through oxidative phosphorylation of “low energy” adenosine diphosphate (ADP) molecules, to “high energy” adenosine triphosphate (ATP) molecules (binding energy), and the subsequent hydrolysis of ATP molecules back to ADP (releasing energy)

7.

What is Aerobic respiration ?

a)

The process of producing cellular energy involving oxygen

b)

Glucose breaks down without oxygen

8.

What is Anaerobic respiration ?

a)

Glucose breaks down without oxygen

b)

Regulate metabolic pathways in energy homeostasis, including glucose, lipid and amino acid

9.

What is ATP ?

a)

Energy for life, the high-energy molecule that stores the energy we need to do just about everything

b)

The process of changing one form of energy into another

c)

The energy required to start a reaction

10.

What are Catalysts ?

a)

A chemical or set of chemicals that are affected by enzymes

b)

A chemical that increases the rate of a chemical reaction without itself being changed by the reaction

11.

What is Chemosynthesis ?

a)

Use of energy derived from the oxidation of inorganic chemicals, such as sulfur released from deep hydrothermal vents, to produce their food

b)

A sequence of reactions in organisms in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds (as in ATP). Also called the Krebs cycle

12.

What is Chlorophyll ?

a)

The green pigment found in the chloroplasts, involved in absorbing light energy for photosynthesis

b)

A chemical that increases the rate of a chemical reaction without itself being changed by the reaction

13.

What are Chloroplasts ?

a)

A cell organelle that produces energy through photosynthesis

b)

An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur
