molecules

28
Q

substance consists of atoms of two
or more different elements.

A

compound

29
Q

An attractive force that keeps atoms
together, whether the electrons are
donated, shared or stolen

A

CHEMICAL BOND

30
Q

This bond is formed when there is an
electrical attraction between two ions
with opposite charges.

A

IONIC BOND

31
Q

Positive ions that are formed by
losing electrons are called _____,
whereas _____ are negative ions that
are formed by gaining electrons. For
instance, Na and Cl to form NaCl
(table salt)

A

cations, anions

32
Q

Two atoms share their electrons. This type
of chemical found is common in carbon –
based organic molecules like DNA and
proteins. It can also be found in inorganic
molecules, such as water, oxygen and
carbon dioxide.

A

COVALENT BOND

33
Q

This bond is formed when two atoms of the same
element or different elements share their electrons
equally.

A

Nonpolar Covalent Bond

34
Q

The electrons are not equally shared, so they are
more attracted to one nucleus than the other. This
is formed when highly electronegative atom shares
unequal electrons with less electronegative atom.

A

Polar Covalent Bond

35
Q

two types of covalent bond

A
  • Nonpolar Covalent Bond
  • Polar Covalent Bond
36
Q

Results from attraction of oppositely
partial charged parts of molecules.
This bond commonly occurs between
water molecules and is also responsible for the zipping of the
DNA double helix together.

A

HYDROGEN BOND

37
Q

refers to all the
chemical reactions that occur in the
body.

A

Metabolism

38
Q

the starting material
and are usually written on the left
side of the chemical equation.

A

Reactants

39
Q

The results of the reaction and are
usually written on the right side of
the equation.

A

Products

40
Q

occurs
when energy is released then absorbed

A

Exergonic reaction

41
Q

happens when energy is
absorbed than it is released

A

endergonic reaction

42
Q

“Synthesis” means what?

A

to put together

43
Q

This reaction occurs when two or
more atoms or molecules are joined
together to form larger or complex
molecules.

A

Synthesis Reactions – Anabolism

44
Q

This reaction happens when two complex
molecules are broken down into smaller
atoms, ions, or molecules.

A

Decomposition Reactions – Catabolism

45
Q

This reaction may consist of both
synthesis and decomposition
reactions

A

Exchange Reactions

46
Q

In this chemical reaction, a product
can revert or go back to being the
original reactant

A

Reversible Reactions

47
Q

usually lack carbon and have simple structures,
so their molecules contain only a few atoms and cannot be utilised by
the cells in complex biological functions.

A

INORGANIC COMPOUNDS

48
Q

These substances are dissolved readily in water such
as ions, sugar, and salt

A

HYDROPHILIC

reaction”, in which monomers are link together to
form polymers while losing water.

A

DEHYDRATION SYNTHESIS

53
Q

are single subunits, which serves as the
building blocks of most macromolecules. When these
are combined, they form large molecules
known as polymers, and release water molecules as
by products.

A

considered as the basic structural component or the “backbone” of
macromolecules.

Thia group play a significant role in the formation of macromolecules
such as proteins, carbohydrates, lipids, and nucleic acids.

A

FUNCTIONAL GROUPS

56

57
Q

These are organic molecules composed of entirely carbon and
hydrogen e.g., Methane (CH4)

A

HYDROCARBONS

58
Q

The study of the chemistry of
biological organisms.

A

BIOCHEMISTRY

59
Q

The study of the chemistry and
different compounds and
processes occurring in living
organisms such as the structures
and functions of biomolecules.

62
Q

This branch of
Biochemistry deals with
all the chemical
manifestations of
metabolism of plants
and animals.

A

ANIMAL AND PLANT
BIOCHEMISTRY

63
Q

This branch of
Biochemistry deals the
relationship between
the different forms of
life and how they
evolved from their
original structure.

A

COMPARATIVE
BIOCHEMISTRY

64
Q

This branch of Biochemistry
deals with the metabolism of
microorganisms such as
bacteria.

A
