Carnivorous plants live in soils that are deficit in |
Water
Oxygen
Nitrogen
Iron
|
2 |
A plant requires potassium for |
Synthesizing proteins
Synthesizing chlorophyll
opening and closing of stomata
None of these
|
3 |
Most vitamins function as |
Catalyst
High energy compounds
Gastrovascular cavity
Transport molecules
|
4 |
A plant requires nitrogen and sulfur for its |
Cell wall
Enzymes
Starch deposits
DNA replication
|
5 |
Carbon dioxide enters the leaves through |
Stomata
Stroma
Gurad cells
Cuticle
|
6 |
The mechanism for ATP synthesis is |
Chemosynthesis
Photosynthesis
Chemiosmosis
Phosphorylation
|
7 |
Carbon fixation refers to the initial incorporation of |
Carbon
Oxygen
CO<sub>2</sub>
Hydrogen
|
8 |
The power house of the cell is |
Ribosome
RER
SER
Mitochondria
|
9 |
Glycolysis is the break down of |
Fructose
Glucose
Lactose
Maltose
|
10 |
Co-enzyme Q is in turn oxidized by cytochrome |
a

11 |
When deprived of oxygen, yeast cells obtain energy by fermentation, producing carbon dioxide, ATP, and |
Acetyl CoA
Ethyl alcohol
Lactate
Pyruvate
|
12 |
In the first step of citric acid cycle, acetyl CoA reacts with oxaloacetate to form |
Pyruvate
Citrate
NADH
ATP
|
13 |
Before pyruvate enters the citric acid cycle, it is decarboxylated, oxidized and combined with coenzyme A forming acetyl CoA, carbon dioxide and one molecule of |
NADH
FADH<sub>2</sub>
ATP
ADP
|
14 |
Which statement about oxidative phosphorylation is not true |
Its functions can be served equally well by fermentation
In eukaryotes, its takes place in mitochondria
It is brought about by the chemiosmotic mechanism
It is the formation of ATP during the operation of the respiratory chain
|
15 |
Which statement about the chemiosmotic mechanism is not true |
Protons return through the membrane by way of a channel protein
Proton are pumped across a membrane
Proton pumping is associated with the respiratory chain
Has no connection with the respiratory chain
|
16 |
The citric acid cycle |
Takes place in the mitochondrion
Produces two molecules of NAD<sup>+</sup>for every glucose molecule processed
It is same as fermentation
Has no connection with the respiratory chain
|
17 |
Glycolysis |
Produces no ATP
It is same as fermentation
Takes place in the mitochondria
Reduces two molecules of NAD<sup>+</sup>For every glucose molecule processed
