Answer:
DNA or RNA: Nucleic acid
Starches and sugars: Carbohydrates
Antibodies: Proteins
Can be utilized for energy if sugars are not available: Lipids
Hydrophobic part of the plasma membrane: Lipids
Glucose and sucrose: Carbohydrates
Explanation:
The DNA or RNA can be described as molecules made up of nucleic acids.
Carbohydrates can be described as biological molecules made up of carbon, hydrogen and oxygen. For example, starches, sugars, glucose, sucrose etc
Antibodies can be describe as a type of proteins which provide the body with immunity.
Lipids or fats are the alternative source of energy if carbohydrates are not present.
The hydrophobic tail of the plasma membrane is made up of fatty acid molecules which are lipids.
Answer:1. Pyruvate carboxylase
2. Phosphoenol pyruvate carboxy kinase
Explanation:
The conversion of pyruvate to phosphoenol pyruvate is catalyzed by two enzymes Pyruvate carboxylase and phosphoenol pyruvate carboxy kinase
1. Pyruvate carboxylase reaction
Pyruvate in the cytoplasm enters the mitochondria. Then, carboxylase of pyruvate to oxaloacetate is catalysed by a mitochondrial enzyme, pyruvate carboxylase. It needs the co-enzymes biotin and ATP.
The oxaloacetate formed has to be transported from the mitochondrial to the cytosol because further reaction of gluconeogenesis are taking place in cytosol.
2. Phoaphoenol pyruvate carboxy kinase (PEPCK)
In the cytoplasm, PEPCK enzyme then converts oxaloacetate to phoaphoenol pyruvate by removing a molecule of CO2. GTP or ITP donates the phosphate group.
The net effect of these two reactions is the conversion of pyruvate to phoaphoenol pyruvate. This circumverts the irreversible step in glycolysis catalyzed by pyruvate kinase (step 9 if glycolysis)
Sweat, mucus, tears, and saliva all contain enzymes that kill pathogens.
Answer:
Yes, mixtures can be separated using a variety of techniques.
Answer:
B) nuclei of gland cells.
Explanation:
DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.
However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.
