autotrophs

Organisms, such as plants, that make their own food are called

heterotrophs

Organisms that cannot make their own food and must obtain energy from the foods they eat are called

ATP

Cellular respiration uses oxygen to convert the chemical energy stored in organic molecules into

a phosphate group is removed

Energy is releasd from ATP when

glycolysis--->Krebs Cycle-->electron transport chain

Which of the following is the correct sequence of events in cellular respiration?

alcoholic fermentation

Which process is used to make bread rise?

Photosynthesis uses carbon dioxide, and cellular respiration produces it

How are cellular respiration and photosynthesis almost oppocite processes?

Chlorophyll

Which of the following is NOT a part of an ATP molecule? Adenine, Ribose, Chlorophyll, Phosphate

used ATP is discarded by the cell as waste

Which of the following is NOT a true statement about ATP? ATP consists of ribose, adenine, and phosphate; ADP forms when ATP releases energy; ATP provides energy for cells; used ATP is discarded by the cell as waste

energy

Which of the following is released during cellular respiration? Oxygen, air, energy, lactic acid.

glucose and oxygen

What are the reactants in the equation for cellular respiration?

oxygen

Cellular respiration is called an aerobic process because it requires

glycolysis

Which of these processes takes place in the cytoplasm of a cell? glycolysis, electron transport, Krebs Cycle, all of the above

lactic acid fermentation

One cause of muscle soreness and fatigue is

true

True/False: (Photosynthesis) uses the sun's energy to convert water and carbon dioxide into sugars

true

True/False: The products of (glycolysis) are 2 ATP, 2 NADPH, and 2 pyruvic acid molecules.

ATP synthase

True/False: Protein structures in mitochondria that act like miniature turbines and convert ADP into ATP are called (electron transport chains)

oxygen

True/False: Unlike cellular respiration can be used to release energy even in the absence of (carbohydrates).

oxygen

True/False: Cellular respiration uses (carbon dioxide) to convert the chemical energy in organic molecules into ATP.

products

True/False: The reactants of photosynthesis are the same as the (reactants) of cellular respiration.

true

True/False: The Krebs cycle produces electron carrier molecules that are important in the (electron transport chain).

C6H12O6+6O2--->6CO2+38 ATP molecules

Write the complete, balanced equation for cellular respiration.

Glycolysis, Krebs Cycle, Electron Transport Chain

2

During fermentation, a cell can extract a net gain of only ___ molecules

oxygen

Cellular respiration occurs only in the presence of ___

fermentation

A high level of lactic acid in the blood is a sign that ___ has occurred.
