Flashcards in Test 2 Deck (36):
1

Producers- are organisms that make their own food and organic matter from inorganic nutrients

Autotrophs (self feeders)

2

Consumers- can not make organic molecules from inorganic ones

Heterotrophs (other-feeders)

3

Sunlight energy=

Photons

4

Products of photosynthesis

Glucose(C6 H12 O6) and oxygen (O2)

5

Products of cellular respiration?

Carbon dioxide(CO2) and water (H2O)

6

Converts light energy into sugar

Photosynthesis

7

The chemical equation for photosynthesis

6CO2+6H2O+light energy➡️C6H12O8+6O2
Carbon dioxide+water+light energy➡️sugar+ oxygen

8

Plants aren’t the only autotrophs what are three others?

Kelp
Cyanobacteria
Other unicellular organisms

9

Algal blooms in lake Eire are caused by?

Farm and industrial run off
Home lawn run off

10

Algal blooms in Lake Erie result in________?

Anoxia
-oxygen depletion in water
-Fish move or die
-hurts economy

11

Where does photosynthesis occur?

Chloroplast

12

Light consist of _______ that contain energy

Photons

13

Photons turn into what in the thylakoid membranes?

An excited electron

14

__________ capture light energy
Such as?

Pigment molecules
Chlorophyll or carotenoids

15

Light reactions in a chloroplast.

Takes in light and water (inside the light reaction part it uses NADP+ and ADP)and converts it to ATP and NADPH. oxygen (O2) is a byproduct. (Light dependent)

16

Calvin cycle

Light independent reaction, enzymes use energy molecules like carbon dioxide, NADPH, and ATP to synthesize glucose and other organic molecules (sugar). Puts back in NADP+ and ADP out puts sugar

17

Why we need photosynthesis?

-all heterotrophs depend on it.
- we can’t make food energy on our own.
-“but I don’t eat my veggies” your food eats veggies.

18

Vegetarians are more efficient
It takes ___lb of corn to make ___lb of beef

4,1

19

Chemical formula for cellular respiration

C6H12O6+6O2➡️6CO2+6H2O+ATP
Glucose +oxygen➡️ carbon dioxide+ water+Energy

20

AROBIC energy harvesting of food molecules

Cellular respiration

21

Like chloroplast _______ has a double membrane

Mitochondria

22

Occurs when there is little to no oxygen available

Fermentation

23

These are high energy electron carriers.

NADH and FADH

24

Input and output of citric cycle

Input= acidic acid, ADP+P, 3 NAD+, FAD
Output= 2 CO2, 2 ATP, 3 NADH, FADH2

25

DNA➡️RNA➡️Protein
What does each of these ➡️ mean

1st one transcription
2nd one translation

26

Makes a copy of the DNA, is the first in the RNA group, happens inside nucleons

MRNA

27

2nd in the RNA group, translates, brings appropriate amino acid to RRNA, happens in the rough ER

TRNA

28

A group of three nucleotides like T,A,C
Start_____ and stop ____ tell it when to start and stop transcribing

Codon

29

The DNA sequence where RNA start to attach is called the

Promoter

30

In bacteria the sequence signaling the end of transcription is the

Terminator

31

The stretch of DNA that is transcribed is called a

Transcription unit

32

DNA= A=_, C=_
RNA= A=_, C=_

DNA= T, G
RNA= U,G

33

The organizer slash lock of the RNA, it happens last in the rna group, allows it to bond to mrna

rRNA

34

Most abundant enzyme on earth, turns carbons into glucose

RuBisco

35

a sequence of three nucleotides in a region of transfer RNA that recognizes a complementary coding triplet of nucleotides in messenger RNA during translation by the ribosomes.

Anticodon

36

Polymerase stops transcription at the end in this

Bacteria
