Bio: Photosynthesis And Cellular Respiration

Front 1

What's carbon dioxide fixation?

Back 1

THe transfer of carbon dioxide to organic compounds

Front 2

What's NADPH?

Back 2

an electron carrier that provides the high-engergy electrons needed to make carbon-hydrogen bonds in the third stage of photosynthesis. In an electron transport chain excited electrons combine with hydrogen ions as well as an electron acceptor called nadp+

Front 3

Calvin Cycle

Back 3

series of enzyme-assisted chemical reactions that produces a three-carbon sugar

Front 4

aerobic

Back 4

metabolic processes that require oxygen

Front 5

anaerobic

Back 5

metabolic process that doesn't require air.

Front 6

glycosis

Back 6

first stage of cellular respiration, glucose is broken down in the cytoplasm.

Front 7

pyruvate

Back 7

ion of a three carbon organic acid

Front 8

NADH

Back 8

hydrogen atoms that are transferred to an electron acceptor called nad+

Front 9

Light absorbing________ are located in the membranes of __________.

Back 9

pigament, thykaloids

Front 10

The carrier protein that transports hyrdrogen ions across the thylakoid membranes and produce atp acts as both a(n) _________ and a(n)________

Back 10

ion channel, enzyme

Front 11

What are the the stages of photosynthesis?

Back 11

First, engergy is captured from sunlight

Second energy is temporarily stored in arp and nadph

third, organic compounds are made using atp nadph, and carbon dioxid

Front 12

During the areobic respiration, pyruvate is first converted to acetyl-CoA, which enters the________.

Back 12

Krebs Cycle

Front 13

Explain how ATP provices energy for cells.

Back 13

When the bonds between the phosphate
groups of an ATP molecule are broken,
energy is released. This energy can be used
by the cell.

Front 14

Explain how artp is produced by electron transport chains during potosynthesis.

Back 14

Excited electrons lose some energy as they
pass through electron transport chains. This
energy is used to pump hydrogen ions,
produced when water molecules are split,
into the thylakoid. Special carrier proteins
that function as both ion channels and as
enzymes transport the now-concentrated
hydrogen ions out of the thylakoid. As hydrogen
ions pass through the ion channel part of
the carrier protein, a phosphate group is
added to a molecule of ADP, making ATP.

Front 15

Explain benefits and uses of lactic acid fermentation and alcoholic fermentation.

Back 15

Fermentation enables cells to continue making
ATP, though in limited amounts, through
glycolysis when oxygen is no longer available.
Lactic acid fermentation is used in the
production of foods such as yogurt and some
cheeses. Alcoholic fermentation is used commercially
in the preparation of bread, wine,
and beer.

Front 16

What's the product of glycosis?

Back 16

Two three carbon molecules of pyruvate

Back 18

phosphate

Front 20

Production fo ATP during photosynthesis requires?

Back 20

1. Energy released from when hydrogen ions ove down their concetration gradient.

2. a carrier protein to catalyze the addition of a phosopate group to a molecule of ADP

3. engergy from electrons passing through electron transport chains
