Answer 1

on student claims that yogurt is made by lactic acid fermentation.Another claims that yogurt is made by alcholic fermentation.testing for which of the following substances could help dentermind whether alcohlic fermentation or lactic acid fermentation was going on?

Answer 2

@Queen_Bee1

Answer 3

do u know when does lactic acid fermentation take place?

Answer 4

or alcoholic fermentation?

Answer 5

no

Answer 6

In the muscles under low oxygen conditions right

Answer 7

but do u know that some organisms like yeast and some bacteria like lactobacillus carry out this fermentation?

Answer 8

nope

Answer 9

okay...see basically there are 2 types of respiration..aerobic and anaerobic. aerobic occurs in presence of oxygen and anaerobic in absence of oxygen.

Answer 10

okay..so now aerobic repiration in short is breaking down carbohydrates to release energy in the form of ATP. With this CO2 is also released.

Answer 11

ok so its a

Answer 12

C6H12O6 (s) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) + heat this is the reaction.go 2 anaerobic respiration. hold on i need 2 find d exact equation for u

Answer 13

yea A

Answer 14

WAit NOOO it D k

Answer 15

ok thx gtg

Answer 16

ok kcool

Answer 17

fermentation is not anaerobic respiration.

Answer 18

Anaerobic respiration is when something besides oxygen is used as the final electron acceptor in the ETC.

Answer 19

fermentation IS anaerobic respiration as it occurs in the absence of oxygen.

I don't think anything but \(O_2\) can be used as the final \(e^-\) acceptor in the ETC because of the potential gradient.

Answer 20

@aaronq You are extremely wrong. Go here: http://biology.clc.uc.edu/courses/bio104/cellresp.htm

Quote "Note that in anaerobic respiration something else is used as the final electron acceptor. For example, there is a group of bacteria called the purple sulfur bacteria that use sulfur in place of the oxygen."

"There are two important ways a cell can harvest energy from food: fermentation and cellular respiration, also known as aerobic respiration because oxygen is used as a “final electron acceptor.” Technically, a third way would be anaerobic respiration, in which a cell (mostly only in some kinds of bacteria) harvests energy from food by using the same chemical pathways as in aerobic respiration, except that some other chemical, such as sulfur, is used as the final electron acceptor. Typically, the kinds of bacteria that use anaerobic respiration live in extremely-low-oxygen environments such as deep in soil or deep underwater, and not only do they not use oxygen, but they are actually poisoned/killed if exposed to it.

Both cellular respiration and fermentation start with the same first step: the process of glycolysis which is the breakdown or splitting of glucose (6 carbons) into two 3-carbon molecules called pyruvic acid. The energy from other sugars, such as fructose, is also harvested using this process. "


Respiration is goes through the ETC. This is where we discuss if it is aerobic or anaerobic. In aerobic respiration oxygen is the final electron acceptor. In anaerobic respiration something else is, frequently a sulfur compound.

Fermentation takes place as a completely separate step and is done in cells that can do aerobic, aerobic and anaerobic, and strict anaerobic respiration.
