Matter is anything that is made of atoms and has mass
Answer: Vacuole
Explanation:
Vacuole is a cell organelle that is lined with membrane and filled with cell sap that serves as a storehouse for many substances especially water. Hence, the cell membrane helps to remove excess water in cells
The phloem sap of vascular plants that moves through the
phloem; transports nutrients through fungi by hyphae, as a result of turgor
pressure. Hyphae are elongated tube-shaped structures that are like garden
hoses. They also have inflexible cell walls that may be strengthened by punctured
cross-walls which are called septa.
Answer:
d. it diffuses into mitochondria to be broken down to generate ATP
Explanation:
When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.
The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.
