Answer:
Sugars provide living things with energy and act as substances used for structure. When sugars are broken down in the mitochondria, they can power cell machinery to create the energy-rich compound called ATP (adenosine triphosphate).

Answer:
limestones, cause they fwea but nah fr no cap its limestones
Sponges have a Contractile vacuole that squeezes out waste
it's a type of membrane that regulate/control the osmotic pressure of the sponge, which will also periodically throw out it's waste

Answer:
Fermentation is important can keep obtaining energy from glycolysis.
Explanation:
In the presence of oxygen, cells will use aerobic respiration to obtain energy in the form of ATP. In these conditions, it can produce up to 36 ATP molecules.
This process has three steps: glycolysis, citric acid cycle and electron transport chain.
During glycolysis, a glucose molecule is broken down into two pyruvate molecules, releasing electrons that are taken up by NAD+ which is converted into NADH, and producing a net total of 2 ATP molecules. The NADH produced during glycolysis and the citric acid cycle will go to the mitochondria and give away the electrons to start the electron transport chain that has Oxygen as the last electrons acceptor, and the NAD+ used to continue glycolysis is regenerated in the process.
In anaerobic conditions (no oxygen), the last electron acceptor is scarce, so the NADH can't give away its electrons and the NAD+ cannot be regenerated, so glycolysis stops, eventually causing cell death due to lack of ATP. To avoid this, cells perform lactic acid fermentation, where the NADH gives the electrons to pyruvate which is then converted into lactic acid. This regenerates the NAD+ necessary to continue glycolysis and keep obtaining some energy to survive until oxygen levels increase.
