Amino acids are organic compounds containing amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid.
Depending on the nature of the side chain groups, three classes of aminoacids can e distinguished:
1. Amino acids with H ond donor and acceptor groups.
Histidine, lysine, aspartic acid, threonine,...
2. Amino acids with donor grups only.
Arginine, tryptophan and cysteine.
3. Amino acids with acceptor groups only.
Asparagine and glutamine.
There are 3 stages in cellular respiration. They are:
1. Glycolysis
2. Kreb's cycle
3. Electron transport chain
Here, Glycolysis produces only 2 ATP whereas Kreb's cycle produces no ATP. Electron transport chain of the cellular respiration produces the maximum ATP.
A tendon is a fibrous connective tissue which is Tough, fibrous, cord-like tissue that connects muscle to bone or another structure, such as an eyeball. Tendons help the bone or structure to move.
The prostate gland is a walnut-sized structure that is located below the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also help to nourish the sperm. The urethra, which carries the ejaculate to be expelled during orgasm, runs through the center of the prostate gland.
RNA is not a lipid among the given options.
A lipid is a substance of biological origin that is soluble in nonpolar solvents. It comprises a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, and phospholipids.
Plants are producers, which means they make their own food. Chloroplasts are organelles found in eukaryotic and plant cells that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
Plants use energy from sunlight to help make their food, but they need chloroplasts to do it.
Hence, in plants, chloroplasts are necessary for Photosynthesis.
The only transport method that can move species against their concentration gradient i.e, from low to high concentration is called Active transport.
Facilitated diffusion only moves species down their concentration gradient i.e, from high to low concentration.
Most bacteria divide by binary fission, a form of cell division in which DNA replication and segregation occur simultaneously. This process involves active partitioning of the single bacterial chromosome and positioning of the site of septation.
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells.
Binary fission begins when the DNA of the bacterium divides into two replicates. The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell.
FALSE. Basophils number will not be increased when parasitic invasion occurs.
Basophils are a type of white blood cell. Although they're produced in the bone marrow, they're found in many tissues throughout your body. They're part of your immune system and play a role in its proper function.
Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. If your basophil level is low, it may be due to a severe allergic reaction.
Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues.
The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, which are the basic functional units of the skeletal muscle.
