The true statement about the arrangement of vascular bundles in monocot is:

B.) VASCULAR BUNDLES ARE SCATTERED IN THE GROUND TISSUE.

Characteristics of monocots are:
1) has one cotyledon
2) veins in leaves are usually parallel
3) flower parts are usually in multiples of three
4) arrangement of primary vascular bundles in the stem is scattered.

Scilla [17]

Answer:

The decomposer has recycled the organic materials in the leaf and released them back into the soil.

Explanation:

Decomposers are the heterotrophic microbes that derive their nutrition by digesting the dead organic matter present in the dead bodies of living beings such as fallen leaves. As a leaf falls from a plant on the land, decomposers present in the soil start its digestion.

The organic and inorganic nutrients present in the leaves are digested into the simpler substances which in turn are released back into the soil. Therefore, decomposers serve in nutrient cycling by releasing substances such as carbon, nitrogen, phosphorus, and sulfur from the dead bodies of living beings back into nature to allow their reuse.

. In which phase of cellular respiration is glucose a substrate?​
vodka [1.7K]

Explanation:

During glycolysis, enzymes act on the substrate, glucose. Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates,  4 ATP and 2 electron carrying NADH molecules.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP.  At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates,  4 ATP and 2 electron carrying NADH molecules.
  • The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate,  2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2,  renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
