Answers ||Best Version||Sure Pass!!!
How are the TCA and ETC related? - ANSWER-The TCA and ETC
are related because the TCA is used to fuel the ETC.
The end products of Kreb's (TCA) cycle are used to fuel the
electron transport chain. In other words, as the Kreb's cycle
(TCA) produces an abundance of reduced electron carriers
(NADH and FADH2), it fuels the ETC. As the electrons are
transferred from NADH/Fadh2 to terminal electron acceptors a
proton motor force is generated, ATP synthase is activated and
up to 34 molecules of ATP can be produced.
In the absence of sugars, are entirely different metabolic
pathways used to process alternative sugar sources (fructose or
lactose)? - ANSWER-No.
No. Additional enzymatic steps are simply required at the
beginning of catabolism to convert complex sugars into the
usable forms of wither glucose or a glucoses intermediate
(glucose-6-phosphate).
Proteases are used to catabolize what? - ANSWER-Proteases are
used to catabolize proteins.

Proteases are used to breakdown proteins (whereas lipases are
used to breakdown lipids).
Excluding sugars, what are the other sources of energy? Which
is highest in energy? - ANSWER-The other sources of energy are
polysaccharides and proteins, the highest in energy is lipids.
Carbohydrates, proteins and lipids can all serve as potential
energy sources in the absence of sugar. Lipids are rich in energy,
often having several reduced carbon molecules (high in
hydrogen content) that can be used in both the TCA and ETC
cycles.
In what organelle does photosynthesis take place? - ANSWER-
The organelle in which photosynthesis takes place in is the
chloroplasts.
Photosynthesis, the process of capturing sunlight and
converting it into usable energy sources, occurs in the
chloroplasts. Chloroplasts are double-membrane enclosed
organelles. Each chloroplast contains the green photosynthesis
pigment chlorophyll.

True or False: As movement requires energy, metabolism can be
defined as a controlled set of biochemical reactions that occur
in only motile organisms in order to maintain life. - ANSWER-
False.
True or Flase: Enzymes slow down chemical reactions to
conserve energy. - ANSWER-False.
What is the term for metal ions that assist enzymes during the
catalysis reaction? - ANSWER-Cofactors are usually metal ions
and assist enzymes during the catalysis reaction.
Define anabolism. - ANSWER-Anabolism is the process of
building up or biosynthesis of macromolecules from small
molecular units into much larger complexes.
In order to convert proteins into amnio acids which metabolic
process would be active? - ANSWER-Catabolism would be active
as proteins are made up of amino acids. Therefore the process
described (proetins into amino acids) is the breakdown, or
catabolism of protein.
Describe the energy transfer process relative to both ATP
andADP. - ANSWER-ATP has the energy (phosphate group) to
