The products of photosynthesis are oxygen and glucose, a simple carbohydrate. ATP is used in photosynthesis but is neither a reactant nor a product. ATP is produced in a different process called cellular respiration. Incorrect answer. Please choose another answer. A cell membrane is a thin layer of molecules that surrounds the cell. Its function is to allow certain materials to enter the cell, yet, keep harmful materials out.
In order to do this, the cell controls which substances can enter the cell through the membrane. The cell membrane is selectively permeable or semipermeable , which means that certain molecules, such as oxygen and water, are permitted to enter the cell. Molecules that are not recognized as helpful are not able to pass through the membrane. Enzymes are catalysts, chemicals that speed up chemical reactions. The conditions inside most cells do not allow reactions to proceed quickly enough to support life.
For example, temperatures inside organisms are not hot enough for chemical reactions to take place quickly. Enzymes increase the rates of biological chemical reactions. Study Online Instantly. Inside cells, sequences of chemical reactions take place to support life. These sequences are known as metabolic pathways. Photosynthesis, respiration, and digestion are all examples of metabolic pathways, or sequences. Photosynthesis is the metabolic pathway that produces oxygen and glucose in organisms with chlorophyll.
Respiration breaks down molecules called ATP for cells to use as energy. Digestion breaks down food to be used to make energy in the form of ATP.
Hydroplasm is not a known metabolic sequence. Chloroplasts and central vacuole are important organelles in plant cells. Chloroplasts contain chlorophyll and are the site of photosynthesis. Central vacuoles are used to store water in plant cells.
All the other organelles listed are important to the function of animal cells and plant cells. Photosynthesis is the process plant cells use to convert oxygen, water and sunlight into a usable form of energy.
The product of photosynthesis is glucose sugar molecules. Glucose molecules are a form of potential energy that can be broken down by an organism to produce energy in the form of ATP molecules. A gene is the basic unit of heredity. Genes are made of DNA sequences and act as instructions for making proteins although not all genes make proteins.
Genes are found on chromosomes. The DNA molecule looks like a twisted ladder and is referred to as a double helix. Each nucleotide contains a sugar molecule and a phosphate group, along with a nitrogen base. Genes are sequences of DNA on a chromosome. In the ribosome, the information coded onto messenger RNA is used to make proteins. During meiosis, gametes sex cells are formed by reducing the number of chromosomes found in somatic body cells by one half. This occurs so that when two gametes, one from each parent, fuse together, the embryo will contain the correct number of chromosomes.
Without meiosis, offspring cells would contain double the number of chromosomes of normal adults and they would not be viable. Biology uses a system of classification to group organisms together based on their characteristics. The levels of classification, from largest most inclusive to smallest most specific , include domain, kingdom, phylum, class, order, family, genus, species.
Prokaryotic and eukaryotic cells both contain DNA. Prokaryotic cells are found in bacteria and their structure is much more simple than eukaryotic cells. Would more or less energy be required to ionize Mo than that used for Cr? In other words, which has the higher first ionization energy, Cr or Mo? Be sure to justify your choice using properties of the atoms.
