microbes, a more general term that includes microorganisms and viruses.
What is the smallest biological unit of life? - ✔️✔️A cell
What are the four main types of macromolecules found in cells? - ✔️✔️Proteins, Lipids,
Nucleic Acids, Carbohydrates
Proteins are formed from various combinations of - ✔️✔️Amino acids
There are how many known forms of amino acids - ✔️✔️twenty

The plasma membrane - ✔️✔️Restricts movement of materials in and out of the cell &
Prevents essential nutrients from escaping
How many carbon atoms are present in glucose? - ✔️✔️6
True of False: The genetic material within a prokaryotic cell is contained within a
membrane-enclosed region. - ✔️✔️False
Only eukaryotic cells contain its genetic material within a nucleus.
True or False: Prokaryotic cells can be subdivided into Bacteria and Archaea. - ✔️✔️True
True or False: Archaea is noted for its ability to survive under harsh conditions.
Correct! - ✔️✔️True
Archaea can often be found in harsh conditions such as high salt levels, high acid
conditions, high temperatures and even oxygen-poor conditions.

apply. - ✔️✔️Animalia, Plantae, Fungi, Protista
Microorganisms classified as Plantae obtain most of their energy by converting
[answer1] energy into [answer2] energy. - ✔️✔️1. Light (sunlight)
2. chemical (sugars)
Which of the following are considered Protista? Select all that apply. - ✔️✔️Algae,
Amoeba
The function of the ribosome is - ✔️✔️Protein synthesis
True or False: Protista retain a unicellular classification, as they are unable to form
tissue layers. - ✔️✔️True

The combination of the cell membrane and the outer membrane is referred to as the -
✔️✔️Cell envelope
The function of the mitochondria is - ✔️✔️To produce energy (ATP)
True or False. All multicellular microorganisms classified as Animalia are autotropic. -
✔️✔️False
True or False: Metabolism is a controlled set of biochemical reactions that occur in living
organisms in order to maintain life. - ✔️✔️True
True or False: Enzymes slow down chemical reactions to conserve energy. - ✔️✔️False
What is a cofactor? - ✔️✔️A cofactor is a small chemical component that assists an
enzyme during the catalysis reactions. A cofactor is usually metal ions.
Define catabolism - ✔️✔️Catabolism is the process of breaking down larger molecules
into useful energy sources.
In order to convert proteins into amino acids which metabolic process would be active? -
✔️✔️Catabolism would be active as proteins are made up of amino acids. Therefore the
process described (proteins into amino acids) is the breakdown, or catabolism of
protein.
Describe the energy transfer process relative to both ATP and ADP. - ✔️✔️ATP has the
energy (phosphate group) to donate while ADP can accept energy in the form of a
phosphate group. Thus, ATP can be reduced (ATP ⟶⟶ADP + Pi) while ADP can be
built into ATP (ADP + Pi ⟶⟶ATP).
From what source do chemotrophs acquire energy? - ✔️✔️Chemotrophs acquire energy
from preformed chemicals found in the environment.
An organism that obtains its source of carbon from inorganic molecules such as carbon
dioxide is referred to as a ____________? - ✔️✔️Autotroph
