Food Molecules
What is the main food molecule for cells?
Glucose
What type of organisms perform photosynthesis?
Autotrophs
What are the three stages of cellular respiration?
Glycolysis, Krebs Cycle, Electron Transport Chain
Yeast makes bread dough rice because it uses _____________________ to produce carbon dioxide and ethanol in gas form, which create bubbles in the dough and make it fluffy
Alcoholic Fermentation
Chemical reactions that absorb more energy than they release are considered to be
Endothermic
Why is ATP useful to cells?
Light-Independent reactions are commonly referred to by the name
Calvin Cycle
Which stages of Aerobic Respiration occur in the Mitochondria?
Krebs Cycle and Electron Transport Chain
Organisms who make energy through anaerobic respiration likely do not have what organelle?
Mitochondria
Chemical reactions that release more energy than they absorb are considered to be
Exothermic
What is the actual name for ATP?
Adenosine Triphosphate
What is the general equation for photosynthesis in word?
Water + Carbon Dioxide => Glucose + Oxygen
What is the general equation for Cellular Respiration in words?
Glucose + Oxygen => Carbon Dioxide + Water
What process produces Lactic Acid?
Lactic Acid Fermentation / Anaerobic Respiration
Identify the products in this reaction: 6H2O + 6CO2→ C6H12O6 + 6O2
C6H12O6 + 6O2
Which of the following reactions directly provides chemical energy for most cell functions?
a. ADP ⇒ ATP + P
b. ADP + P ⇒ ATP
c. ATP + P ⇒ ADP
d. ATP ⇒ ADP + P
d. ATP ⇒ ADP + P
In the cell, which organelle converts solar (light) energy into chemical energy stored in sugar?
Chloroplast
How many hours per day do plants use molecular oxygen in aerobic respiration?
24 Hours
One factor that contributes to the fatigue of a long-distance runner is the accumulation of lactic acid molecules in muscle cells. This lactic acid is produced most directly as a result of
Anaerobic respiration / not enough oxygen getting to muscle cells
If the activation energy of a biochemical reaction is lowered, then
the reaction will occur faster
ADP has _______________ phosphate groups
2
How many turns of the Calvin Cycle are required to make 1 molecule of glucose?
6
What are the products of the Krebs cycle?
2 ATP
8 NADH
2 FADH2

a. glycolysis can occur with or without oxygen
b. glycolysis occurs in the mitochondria
c. glycolysis is the first step in both aerobic and anaerobic respiration
d. glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate
b. glycolysis occurs in the mitochondria
The molecule that an enzyme binds to is known as its
substrate
