2 ATP's

The Kreb's cycle produces...

2ATP, CO2, NaDH, and FaDH2

How many ATP's are produced during the electronic transport chain?

34 ATP's

Which molecule has a higher potential energy?

ATP

The light dependent reaction produces:

ATP and NADPH

_____ have chloroplasts and produce _____ as a waste product, whereas _____ ingest their food and have _____ as a waste product

Autotroph; oxygen; heterotrophs; carbon dioxide

Most common agricultural plants are...

C3

Which plants are considered drought resistant?

C4

What by-product of cellular respiraiton is required for photosynthesis?

Carbon dioxide

The chemical reactions of photosynthesis occur in which cellular organelle?

Chloroplasts

We use energy in many ways. What is one thing we cannot do to energy?

Destroy it

In photosynthesis the plant produces its food...

During the light-independent phase

Identify the stage of cellular respiration where glucose is split into two molecules of pyruvic acid?

Glycolysis

How do we know green light is not absorbed by chlorophyll?

Green light is the wavelength of light that is reflected instead of absorbed by the chloroplasts.

What is the role of light in photosynthesis?

It excites/energizes electrons

Identify the role of carbon dioxide in photosynthesis.

It is split to become incorporated into sugars

Can cell respiration proceed without glucose?

No answer text provided

Alcohol is a waste product produced by yeast in the presence of sugar and the absence of ________.

O2

Why do some leaves change color (red, yellow, orange, etc.) in the fall?

The chlorophyll molecule breaks down and other pigments now become visible.

What molecules link the light reactions and the Calvin cycle?

The electron shuttles

Yeast is used to produce beer and wine but can also make bread rise. All of these processes involve the production of alcohol. Explain why you can eat bread and not get drunk.

The heat of cooking bakes out the alcohol

Where do the molecules used as the inputs of the Calvin cycle come from?

They come from the light reactions

Which of the following best describes the chemical equation for photosynthesis?

Water + Carbon dioxide + Energy = Sugar + Oxgen

What is aerobic fermentation?

Photons are:

both

Which processes can be carried out by producers?

both photosynthesis and cellular respiration

Which stage of cellular respiration requires oxygen that you breathe?

both the citric acid cycle and and the electron transport chain require oxygen

The Calvin cycle is part of

during the light-independent phase

During which stage of cellular respiration is the majority of the ATP produced?

electron transport chain

Autotrophs are organisms that feed themselves or produce their own food. What is the food that autotrophs make for themselves?

glucose

Which metabolite produces the most energy during cell respiration?

glucose

Identify the stage of cellular respiration that occurs entirely outside of the mitochondria.

glycolysis
